Got to thinking with all of the Bachmann steam out there has anyone of you done the measurements to see if any of the drivers could be exchanged into another loco. What I am interested in is seeing if I could find a set of traction tired drives for my Bachmann 2-6-6-2. Anyone know if the drivers from a 2-8-0 or a 2-10-2 made by Bachmann would be the same diameter? I know I could use the BFS but wondering if they reengineered the drivers for each loco or if they just made them fit what they had around.
It would help if you measured the 2-6-6-'s drivers and reported what size they are. Then others can with the flangemeasure their engines. Measure the diameter over the tread and also with the flange.
And the axle thickness. Seems logical they'd use common parts, but Bachmann's HO trolley and cable car use completely different mechanisms, despite the fact that the power trucks are the same wheelbase. So don't count on it. The cable car is the superior mechanism, by the way.
Being that the actual locomotive was low drivered at 56 inches and if Bachmann stayed close to that then the 2-10-2 might be the same as it. I think the 2-8-0s and the 2-6-2s are bigger drivers. Probably though the best solution is a very thin coat of BFS on one pair of drivers on each set. Thin so as not to cause the other drivers to lose rail contact.
Increased running time (over 30+ hours) improves the performance of the Spectrum 2-6-6-2's (both runs). Have fun with it......... Shades
At least five cars to seven cars, but this is also dependent on your track work and layout. Metal wheel sets on the cars is also a pre-quisite for improved performance Fifteen cars is unreasonable to ask for and unrealistic. Have fun with it.... Shades
If the 2-10-2 is reasonably accurate, then it should have 57" drivers. I believe the Spectrum 2-8-0 has drivers that are over 60".
