Tramlad Posted March 8, 2011 Share Posted March 8, 2011 Having spent many happy years with 4mm trams, the time has come to make an attempt at "o" gauge trams. I'm planning a modern image Nottingham style city tram, but the bit of advice I'm looking for is the o gauge motor bogie and 3 or 4 trailing bogies I'll require to complete the build. Any help or guidance but be appreciated as I cant seem to find any advice on modern image tram modelling. Link to post Share on other sites More sharing options...
PLD Posted March 8, 2011 Share Posted March 8, 2011 Modern Image ('second generation') tramway modelling is a very small niche within what is already a niche market! - I can't think of a single layout based on second generation UK operations. Similarly 7mm scale is a small minority squeezed between 4mm/3.5mm (OO/HO) and larger sizes. In 4mm you have a few options but in 7mm the only rolling stock available was a brass kit for a Manchester Metrolink T68 (10xx number series) car. To power a Nottingham Incentro style car the best option would probably be to look at Terry Russell's trucks. I reckon one of the longer wheelbase 4 wheel types in each end unit with an unpowered version in the centre unit would be a close resemblance of how power is distributed on the prototype...

Red Devil Posted March 8, 2011 Share Posted March 8, 2011 No idea of the Nottingham cars wheelbase etc, but thought of these http://home.waterfro...sem/bbeetle.htm black beetles in 7mm gauge format, might work? Wasn't there a 7mm kit for a Croydon Car? Link to post Share on other sites More sharing options...
Engineer_London Posted March 9, 2011 Share Posted March 9, 2011 Just a relevant footnote on the 7mm Croydon model. I have a couple, awaiting a distant future when modelling becomes possible. The recommended motor bogie is an ABC product, with a single axle-hung motor, to fitted at the centre of the tram under the articulation. Such a bogie would be supplied with wheels to Gauge 0 railway standards which aren't the same as the 7mm tramway wheel TLRS-preferred standards [http://www.tramwayinfo.com/Models/Howto/Stand7.htm]. I've planned a different route for powering the Croydon models when built, aiming to scratchbuild suitable motor bogies [one motor per axle, simple H-frame, compensated] for the outer ends of the vehicle, and with a free-running 'truck' under the articulation.
