I have a black geared Brill Trolley which runs perfectly in one direction and then runs in the other direction and stops. It then won't run in any direction. There is an exploded diagram of the Brill Trolley and instructions for lubrication and maintenance plus trouble shooting tips in the box. The metal wheels are clean. I would like to know how to carefully remove the body so I can inspect the motor mechanism and gears to hopefully rectify this problem.
Thanks,

No alternative couplers supplied in the box.

I have two Bachmann N Scale Cat. No. 19397 Jackson Sharp Open-sided Excursion Cars fitted with Knuckle Couplers. I wish to use my Hornby Minitrix  N201 Fowler 0-6-0T Dock Tank and Kato Blue Electric Locomotive from the Kato 10-502-2 Mini Convex Freight Train Set to haul them. I therefore wish to fit the Excursion Cars with the Conversion Couplers  (N Scale Universal) as shown on the e store Universal N Scale Parts page. The Conversion Couplers come in three lengths - long, medium and short - but I am not sure which size I need. I would like advice on which length would be appropriate to use.
Thanks
