I just purchased a g scale rr crossing. I'm having a problem with on side. The crossing bar comes down when a train passes as it is supposed to, but one side doesn't does not raise by itself. I tried switching the "trees", but it makes no difference the same side stays down. Any ideas what the problem could be? Thanks.

Is it possible to convert an Annie 4-4-0 to battery power and if so, does anyone have plans they could share? Thank you.

Yes, the little springs are the and Yes, I have them mounted to the truck. How would that keep them from operating? I guess I'll try to body mount them. To do that I have to cut part of the truck off. I hope they work after this doing that. Bachman should have supplied instructions. The screws or push pins also. Didn't have this problem with other couplers. Wish I stuck with them. I'll let you know how to things come out. Thank you for your input.

Thanks Mark. There is no screw or push pin. I put the coupler in the coupler but x and the the whole assembly clips into the truck. My big problem is that they won't couple. I put a Bachman magnet under the track. Didn't help.

This is an older M.K. Explorer set.  After removing the Rapidos and the spring, all there is left in the box is a  plastic pin. Do I need to use the spring? I purchased quite a few of them these and none came with instructions. Do they have to pass over a magnet in order to close? I thought the magnet was for uncoupling? Thank you.

I just installed Bachman's magnetic activated couples on a McKinley Explorer set. How do they work? They will not "close" and the cars do not couple. Also, they are loose in the gear box. Is there any way to tighten them up?
