'CHARD Posted March 31, 2015 Share Posted March 31, 2015 Probably, yes. I've never looked at a 92, but I assume as a much older model design, it uses a simple motor, and is a relatively lightweight model. The 66 uses a centrally mounted can motor, in a heavy metal chassis casting, and is geared to run at prototypical speeds. Link to post Share on other sites More sharing options...

RMweb Premium melmerby Posted March 31, 2015 RMweb Premium Share Posted March 31, 2015 Many old locos (especially Hornby) are grossly overgeared with locos reaching scale speeds well in excess of what they would have in real life. This is possibly a hangover from Tri-ang days, when all trains seemed to race around! The old XO4 motor in a steam outline loco with just 20:1 gearing was pretty fast! e.g 100mph tank engines, 80mph goods locos etc. (Ignore 9F please!)+ Todays models are generally more in keeping with the real thing. e.g Hornby 42XX tank goes about 40mph scale speed. My Bachmann class 47 does about a scale 80 mph (central motor, 12 wheel drive, heavy chassis) Keith Link to post Share on other sites More sharing options...
