May 2021 News

Rolling Stock Updates

The Dm3 was fitted with replacement mirrors and windscreen wipers in May. There is some confusion about the part number for these Roco items, the number given on the instruction sheet seems to be for different components (if website searches are anything to go by), and Roco’s own website is not very helpful! So, we have modified and fitted Jeco components instead. We also need to fit new handrails, but we may need to make these here. The 0,5mm rod would be very suitable for most applications, but there are some items that need stanchions between the ends, and that is where it gets tricky! We’re still investigating that one.

N 1304 lost one of its buffers during recent work, and it is a very flimsy piece of metal. A repair was made at the beginning of May, by drilling a 0,5mm hole in the stock and buffer head, inserting a rod, flanked by a tube (from the materials bought last month), and then gluing it all together! It looks messy, but if it holds, then we’ll leave it alone. Otherwise, we shall replace all four! An order has been placed for a replacement set, but the items is not in stock, and we don’t know for how long.

Catering carriages R4R 5441 and 5447 arrived in early May. These are such limited items from HNoll, that they were not to be missed at any cost. One will go into the existing 1980s InterCity train; the other will be a reserve until more carriage types arrive from HNoll, and then it will go into that set. (The next models hinted from HNoll are the series-2 A7 and B7; two of each of these would go with the ‘extra’ R4R to make an InterCity train. Then, longer term, one each B2 and B4 would be added to make a seven-carriage train. At this time, a second B2 and B4 would be added to the existing set, and one of the (Roco) B7 replaced by a HNoll AFM7! That’s the intention, anyway! If HNoll produces series-1 A7/B7, then that could see the withdrawal of many of the Roco carriages.)

Manufacturer News

HNoll has advised that delivery of the remaining catering carriages, and the Connex/TKAB couchette and sleeper carriages are expected to Sweden early June. The earlier sleeper and couchette carriages are starting to sell out. Some carriages are already out of stock; there is an increase in demand for these mainly abroad, accounting for about 50% of sales at the moment.
PCX87 (Premium Classixx 1:87 scale) has now advertised Volvo 740 sedans and estates, of the 1985 year model. This raises even more questions about the proposed Minichamps 1986 year models, which have production dates advertised for early 2022!

Koenigsegg specialises in full scale ‘sports’ cars, hand-made, and a good production run will see about 20-30 vehicles! We’ll say nothing about the price! And now, the ultimate H0-scale model car for your Swedish diorama… from the Koenigsegg website, you can buy a 1:87 scale model of their Agera RS (from 2015). Only 25 (1:1-scale) units were made, so a diorama would be closer to average with a Volvo P1900 than one of these! Nevertheless, despite being too modern for our epoch, one has arrived! Koenigsegg is based in Ängelholm (home of the Swedish Railway Museum)!

Other News

In recognition of a particular trend in Sweden, and wanting to do something with the four abandoned model car conversion projects (Saab 900i, Volvo 544, Volvo 240, and Volvo 740), they will all be rough-finished to represent the infamous ‘A-Traktor’, which is a common sight. (A-Traktor is a motor vehicle consisting of a converted car, which is designed to tow other vehicles or work equipment and must be equipped with a coupling device. The maximum speed of the A-Traktor may not exceed 30 km/h, and they carry a large red triangle on the back. They can be driven without a full driving licence and without attaining the age for a full driving licence! They are more popular with teenagers than with their intended users! Try selling that idea to the British DfT.)

Nyheter, Maj 2021

Dm3 utrustades med utbytesspeglar och vindrutetorkare i maj. Det finns viss förvirring om artikelnumret för dessa Roco-artiklar, numret som anges på instruktionsbladet verkar vara för olika komponenter (om det är något att söka på webbplatser), och Rocos egen webbplats är inte särskilt hjälpsam! Så vi har istället modifierat och monterat Jeco-komponenter. Vi måste också montera nya ledstänger, men vi kan behöva göra dessa här. 0,5 mm stången skulle vara mycket lämplig för de flesta applikationer, men det finns några föremål som behöver stötar mellan ändarna, och det är där det blir knepigt! Vi undersöker fortfarande den.
N 1304 förlorade en av sina buffertar under det senaste arbetet, och det är en mycket tunn metallbit. En reparation gjordes i början av maj genom att borra ett 0,5 mm hål i komponenterna, sätta in en stav, flankerad av ett rör (från de material som köpts förra månaden) och sedan limma ihop allt! Det ser rörigt ut, men om det håller, lämnar vi det i fred. Annars ersätter vi alla fyra! En beställning har gjorts för en ersättningssats, men varorna finns inte i lager och vi vet inte hur länge.
Serveringsvagnar R4R 5441 och 5447 anlände i början av maj. Dessa är så begränsade föremål från HNoll att de inte skulle missa alls. En av dem kommer att gå in i det nuvarande 1980-talet InterCity-tåg; den andra kommer att vara en reserv tills fler vagntyper anländer från HNoll, och sedan kommer den att gå in i den uppsättningen. (Nästa modeller antydda från HNoll är serie-2 A7 och B7; två av vardera skulle gå med den “extra” R4R för att göra ett InterCity-tåg. Sedan, på längre sikt, en varje B2 och B4 skulle läggas till för att göra en sju-vagnars tåg. Vid denna tidpunkt skulle en andra B2 och B4 läggas till den befintliga uppsättningen, och en av (Roco) B7 ersattes av en HNoll AFM7! Om HNoll producerar serie-1 A7/B7, kan det se återkallande av många av Roco-personvagnarna.)

March 2021 News

March got off to a slow start. We were preoccupied with house viewings, a new (second-hand) car (from a dodgy dealer, with some technical issues), and a ‘name-day’ celebration.

Rolling Stock Updates

N 1304 is so near, yet so far from completion! For testing, we purchased a GaugeMaster Combi (a very basic controller with plug-in transformer) from a UK supplier, but we weren’t ready to use it immediately.
The brake rigging was removed in March and cleaned up. Then the metal rods were replaced by plastic rods and the risk of short-circuits across that means was eliminated. 0,5mm plastic rod is a very difficult product to work with and replacing the four rods took over three hours. It is also very soft, so they are easily bent out of shape!
We took a fresh look at the handrails that support the front steps. The design really does suggest a trip-hazard, so by changing the height, and modifying the fixing point, we have been able to fit these without upsetting more of the loco. They have been painted dark grey, so that they are slightly visible against the black background. This has worked so well that most of the other handrails have been repainted in this way.
Fitting the front coupling was also a struggle. We needed a spare offcut of metal that was wider than 5mm and longer than 14mm, into which we could tap a thread for a fixing screw, and turn up each end so that it would fit inside the frames. We had nothing of this sort, so we used a more narrow piece which was quite weak having been tapped. Then, we ‘butchered’ a ‘cap’ for the UK 3-pin plug, and made a suitable brace to fit into the frames, to carry the coupling. The coupling pocket has been damaged, however, and this will be replaced at a later date.
Returning to the Controller; this arrived mid-March and we were able to properly test the loco’s performance, not just the motor, but also (and especially) the valve gear. As expected, the first run was virtually stationary, so several modifications were made. In the process, the driver side motion virtually fell off! The cause was the still faulty top glide on the crosshead, and this had damaged the slide bars. We also found a faux-pas on our part in that on the fireman side, the eccentric rod had been fitted closer to the wheel than the return crank, so the wheels could not go round! The fireman side valve gear was adjusted and corrected and with none of the other side attached, the loco ran under power quite satisfactorily.
The driver side was to prove a little more problematic, however. During the short run under power, the coupling rod fell off, which was not a problem, just amusing. It meant that we could start from scratch, and having learned a few lessons, we were able to do this with more professionalism. Unfortunately, the now-damaged slide bars were really beyond repair (we had several attempts), but after a couple of hours, we had to resign to the fact that they needed to be replaced. Thankfully, MJ-Hobby had a twin-pack of etched parts in stock (giving us a total of four pairs of slide bars and loads of other spare parts). This was of course, very frustrating, but it led to something much better; see our next item!
The new etched sheets arrived quite quickly, and one of the slide-bar assemblies was extracted, shaped, and filed so that it would be an easier fit. Once fitted, a little glue will stop it rattling, but this seems unlikely, anyway! Everything was fitted in one day, but not to the pivot for the connecting rod big end or the return crank. This was because we needed to allow time for the glue to dry where we had used a washer instead of the now-lost nut on the expansion die block. As work continued, more irritations became apparent. The pivotal pin for one of the connecting rods’ big ends unscrewed as the wheels went round and that had to be glued back in. This, in turn had damaged other parts of the valve gear, and a whole day was spent on remedial work. To be safe, we made this modification to the other side, also.
We have lost count of the number of times that we have had to clamp and re-glue the fitting for the expansion die block, or the front of the radius rods to the cylinders (not required on genuine steam locos, of course), or even the slide bars to the cylinders, and these corrections are ongoing as March drew to a close.

Dm3 1221+1240+1222 is one of the later versions (Marshall lights, revised position of driver side door, extended roof ventilation openings, etc) and the Roco model in plain brown has been desired for some time. At the time that we needed to order the spare part for the N-loco, we had a casual look at the second-hand models also available, and there it was, the Dm3 loco that we wanted! For us, this is the perfect Epoch-IV version of this loco, others have either older lighting and door layouts, or have more modern LKAB/MTAB logos on (or even more modern (blue) liveries)!
The prototype for this loco, sadly came to an abrupt end on March 19th, 1993, when iced-over points threw it off the track and down the side of a mountain near Katterat. The driver and has passenger (his young daughter) suffered only minor injuries because the snow came through the broken windows and cushioned them from any serious harm! The loco had to be scrapped on site; on the side of the mountain! (We wonder if Roco was aware of this fate when they produced the model?)

SCENIC MODELS are also in the news this month, with the arrival of some new cars and a lorry. Two PCX87 Volvo 240 models have arrived (see Manufacturer News, below), and a Scania lorry in Swedish postal livery. (Our only current Swedish postal lorries are Iveco; not very Swedish!) Ironically, this model arrived in a package covered in no fewer than 31 postage stamps…! We also took delivery of a Wiking Chervolet Malibu, which is the nearest imitation we can find (in H0-scale) of the Chevrolet Impala; the car used by the Jönsson Gang in the classic Swedish films, “Jönssonligan…”! We will alter the appearance of the model to match the film car!

Manufacturer News

NMJ has released the second wave of Y1 railbuses, SJ blue with the air-intake boxes on the sides. We’re a little disappointed that the orange version has not been produced with these intakes; that is the condition that applied in 1990 when Sweden was first identified as the country to model.

BoS has released a Volvo 265 ambulance (stretched chassis), but the livery is not especially Swedish.

Minichamps has added to their range of proposed Volvo cars, the 480 coupé in four colours (1987 year model) and the 850 sedan in four colours (1994 year model). If the latter is produced, it will be probably the most modern Swedish car in H0-scale!

PCX87 has released limited models of the Volvo 240 sedan and estate (1989 year model) ahead of the 1986 ones proposed by Minichamps. One of each has arrived, and close inspection reveals some disappointing details discrepancies. One of the most classic features of the 145/245 estate is the top of the rear passenger door which drops away from the roof-line; this is not recreated on the PCX87 model! Our photos compare this with a Brekina 145 model (which has other faults)! Other discrepancies are less obvious. (Compare the differences, below!)

And finally, if you want to decorate the scenic area of your Swedish diorama with moose, then Preiser produces a set; but they’re males only (with the antlers, of course). For females, the Canadian supplier miniprints.ca has some convincing models (and more males, of course).

Nyheter, mars 2021

N 1304 är så nära, men ändå så långt ifrån att vara redo! För testning köpte vi en GaugeMaster Combi (en mycket grundläggande styrenhet med plug-in-transformator) från en brittisk leverantör, men vi var inte redo att använda den omedelbart.
Bromsarna avlägsnades i mars och städades. Metallstavarna ersattes av plaststavar och risken för kortslutning över det sättet eliminerades. 0,5 mm plaststav är en mycket svår produkt att arbeta med och att byta ut de fyra stavarna tog över tre timmar. Det är också väldigt mjukt så att de lätt böjs ur form!
Vi monterade nya ledstänger för de främre trappstegen. De har målats mörkgrå så att de syns mer mot den svarta bakgrunden. Detta har fungerat så bra att de flesta andra räcken har målats om på detta sätt.
För att passa den främre kopplingen hade vi inga lämpliga bitar av metallskrot, så vi gjorde ett plaktiskt stöd för att passa in i ramarna, för att bära kopplingen. Kopplingsfickan är dock skadad och kommer att bytas ut vid ett senare tillfälle.
Sedan var vi redo att använda den nya styrenheten. Vi behövde testa motorn och ventilkugghjulets frikörning. Motorn är bra, men det finns många, många problem med ventilväxeln, och ständiga justeringar tar mycket lång tid. Vid ett tillfälle kunde vi köra loco med ventilväxeln saknas från ena sidan, helt! En uppsättning glidskenor skadades utan reparation, och vi var tvungna att köpa en ny etsad bit. Detta kom på ett ark etsade komponenter, med många, många andra delar.
De nya etsade arken anlände ganska snabbt, och en av glidstångsenheterna tillverkades så att den skulle passa. Sedan skruvade man bort den svängbara stiftet för en av vevstakarnas stora ändar när hjulen gick runt och det måste limmas in igen. Detta i sin tur hade skadat andra delar av ventilväxeln och en hel dag spenderades på att avhjälpa arbete. För att vara säker gjorde vi den här ändringen till andra sidan också.
Vi har tappat räkningen av antalet gånger som vi har haft att klämma fast och limma tillbaka beslaget för expansionsblocket eller framsidan av radiestavarna på cylindrarna (naturligtvis inte nödvändigt på äkta ånglokaler), eller till och med glidstängerna till cylindrarna, och dessa korrigeringar pågår när mars närmade sig slutet.


Dm3 1221 + 1240 + 1222 är en av de senare versionerna av denna klassiska lokstyp (Marshall-lampor, reviderad position för förarsidans dörr, utökade takventilationsöppningar osv.), och Roco-modellen i vanlig brun har varit önskvärd under en längre tid. När vi behövde beställa reservdelen till N-lok såg vi en avslappnad titt på begagnade modeller som också fanns tillgängliga, och där var det Dm3 lok som vi ville ha! För oss är detta den perfekta Epoch-IV-versionen av den här loken, andra har antingen äldre belysning och dörrlayouter eller har mer moderna LKAB/MTAB-logotyper på (eller ännu mer moderna (blå) färger)!
Prototypen för denna lok slutade tyvärr plötsligt den 19 mars 1993, när iskasta punkter kastade den från banan och nerför sidan av ett berg nära Katterat. Föraren och passageraren (hans lilla dotter) fick bara mindre skador eftersom snön kom genom de trasiga fönstren och dämpade dem från allvarlig skada! Lok måste skrotas på plats; på bergets sida! (Vi undrar om Roco var medveten om detta öde när de producerade modellen?)


Icke-järnvägsmodeller är också i nyheterna denna månad, med ankomsten av några nya bilar och en lastbil. Två PCX87 Volvo 240-modeller har anlänt (se våra engelska nyheter från denna månad) och en Scania-lastbil i svensk postleverans. (Våra enda nuvarande svenska postbilar är Iveco; inte särskilt svenska!) Ironiskt nog kom den här modellen i ett paket täckt av inte mindre än 31 frimärken …! Vi tog också emot en Wiking Chervolet Malibu, som är den närmaste imitationen vi kan hitta (i H0-skala) av Chevrolet Impala; bilen som används av Jönssonligan i de klassiska svenska filmerna! Vi kommer att ändra utseendet på modellen så att den matchar filmbilen!
