LGB 20140 Feldbahn steam engine

Dan,
This pic shows (on left) an old-type Feldbahn mechanism (very stripped-down), and at right the new type.... you can see that the motors are quite different in shape (old type has flattened casing, new one is cylindrical and slightly shorter, so I don't think they are interchangeable). The new-type mechanism still only has direct motor drive to the rear axle, but it replaces the old rubber belt transmission with a new longitudinal driveshaft with bevel gears at each end, to transmit the drive to the front axle.
Interestingly, the new type motor is stamped "Maerklin" rather than Buhler, but it may well still be a Buhler-made unit....?

As far as I am aware, the entire power unit/chassis from a new type loco is a direct swap for the old type, even though the individual parts may not be.
Do note that the apparent size difference in the photo (eg: when looking at the cylinders) is entirely due to perspective - the stripped-down chassis is lying on the box-lid but the new version is a complete inverted loco, thus the working parts are much nearer the camera!

Thanks Jon. So the drive shaft may have a longer life span than the timing belt. Especially if long running sessions are the norm.
