I'm not sure how much Accy UK talk to Accy US regarding manufacturing of the models. I haven't heard of any problems with the Accy Whitcombe diesel - although that's just a Bo-Bo with whizzy cranksAs I understand it, making the tooling for the body mouldings is the very expensive part of bringing a plastic loco into production. This news is therefore very good. As they will have made most of the investment for this model I'm sure they will be working hard to bring the completed loco to the marketplace as quickly as they can. Its fair to say that Accucraft haven't got a lot of experience of drive trucks for diesels. They do make an 0-6-0 diesel shunter. The chassis on the first version wasn't great; it worked well but it wasn't strong and the chassis didn't last well. The latest version of the same chassis is much improved and should last well which bodes well for this model. Whatever Accucraft do the drive trucks will last longer than the Aristo GP40 trucks which were very prone to failure. I suggest Accucraft should use the USA Trains power trucks as they are a well known and proven unit. The split gears on these units date back to early production and I can't recall a problem with the later production locos.
Anyway - I'll have a GP60M in warbonnet please!
Yes, I think he was - which is why I drew the difference about US/UK. They had drive train issues with the IoM Viking as well, which was a bit of a shame.I think Chris might be referring to the abomination (chassis-wise) that is the Baguley Drewry?
Actually, that is a little harsh.. The chassis is fine, it is the way the drive is transferred from the motor, that is not good..
Yebbut, that's Accy UK - they are separate entities
I've frequently commented on the fact that in this scale, manufacturers seem to ignore the split axle concept which, IMHO, could be used to advantage. If the bogie cross-members were of an insulating material, and if the bogie side-frames where metal (e.g. casting with bronze bearings) and the axles were split, then the pick-up could be through the wheel to the bearing without any need for wipers. (I'm ambivalent on skates - don't use 'em personally).Chris:
The USAT axle problem exists today, never fixed, slightly improved.
There was nothing wrong with the actual truck castings or design in the Aristo GP40, they came with counterfeit motors that had inferior insulation on the motor winding wire which caused shorting in the motors. Replacing the motors solved the issue.
These are fine points, but don't use mistaken information to support conjecture about the Accucraft loco. I do hope if they copy any design, they do favor the USAT which had a more robust power pickup with the whiskers on the axles, pickup on axle tips and skates.
In that case, yesRhino, the USAT locos do this with a brass/bronze bushing in the sideframe already.
In the "consumer" lines of locos, like USAT, Aristo, Bachmann, LGB, making metal sideframes is probably too expensive, to get great detail.
Also a negative is shorts from derailments will be more common/severe with the ability of a metal sideframe to sit down on a powered rail.
So I take it your comment means for other manufacturers to adopt the USAT practice on diesels?
I suppose it would be possible to put a plastic detail outer on a simple metal bogie side frame - in theory. However, my recollection of US diesels is that the frames are frequently of an open type construction (there's probably a name for it).In the "consumer" lines of locos, like USAT, Aristo, Bachmann, LGB, making metal sideframes is probably too expensive, to get great detail.
"Yes, the final UK RRP still has to be decided but is likely to be between £550 and £600 and we will be distributing them. Liveries as per the US news bulletin. Please let us know if you are interested.
