Although I really enjoy my climax I was always disapointed in the pulling power of it. I decided to buy a new power truck from Bachmann and build a three truck climax. The result worked out great. It now pulls a load with no problem.
it's really pretty straight forward. I use a Shay tender I had left over and built up the under frame with plastic trying to match the original as much as possible. took the pilot step off the original and used on the rear of the new truck. Got extra driveshaft parts from Bachmann for the rear of the second truck. Put my batteries in for weight and there it is.
Nice. Very nice. I've never really liked the looks of the B'mann climax; it looked very back heavy to me. For some weird reason, however, adding an extra truck to the back seems to bring it back into balance. I don't know how that works out, but it's made for a very attractive locomotive.
