Lima N-Gauge Class 86

Recently I acquired a Lima N-Gauge Class 86, not to run as a serious locomotive but in part out of curiosity about older N-gauge motor mechanisms, and possibly to experimentially modify. It was sold as a non-runner with a missing coupling; the coupling was easy enough to replace with one from Kato, and the non-running was caused by the brush having come loose from the motor (luckily it was still held in place against the motor body by the spring, though I do have some spares).

It runs somewhat better (or less badly) than I expected and seems to cope with the Kato pointwork reasonably well. It definitely needs some maintenance, which I'll get round to some time. Here's a video of it running on my temporary layout:

The motor is the ancient pancake type and mounted directly on one bogie, which means there's not much space for it to turn inside the body, which gives it a tendency to derail on tighter curves. The electric pickups are from the non-motorized bogie only, which increases the risk of stalling, particularly across points.

Here's someone else's version of the same model which seems to run much better:
