What did you do to your trains today?

First actual run of the modded ex Annie chassis, pulling the same load as Salty on a similar track setup. While it runs more smoothly than him despite the weird traction tyres, the OG DU seems a bit weaker on 1.5V compared to other "Thomas types". In addition to its lower speed, there are points where it will "shut down" as before due to voltage drops even though the wiring is fine. Reinstalling the rear counterweight didn't help much. Can't really replace the DU since I don't want to trim the negative contact on my only good spare one, and the one with the stiff switch has an incompatible drive gear. Replacing that with the corresponding TOMY part didn't work either. Some of the shells I made for this chassis in 2021 make it perform better than others; the best being the Class 08, followed by the orange diesel. In a funny way, the Daisy shell somehow makes the chassis "act" like her and the switch can't stay in the on position. Then again, they were all designed when the chassis wasn't working and she didn't seem to have that problem.
