Reply to "MTH Railking Camelback - need help please."

Thanks for all of the replies.

Soo Line: Yes, I have cleaned the track, and the rollers, and the wheels of this loco with denatured alcohol (we call it Mentholated Spirits here in Australia). I am now leaning toward something to do with the transformer. I recently received another giant American steam loco I won on a Stouts auction at the end of January.....a Railking Cab Forward with PS1. This behemoth runs perfectly using the same Lionel transformer, as do all of my other PS1 diesel loco's.

Chuck Sartor: Thanks for the info. The MTH instruction book that came with the Camelback clearly shows this transformer (Lionel RS-1) listed in their chart at the end of the manual as being suitable. I am starting to believe what you say may be right. Thank you.

D500: Thanks for the explanation on transformers and their abilities, or inabilities in this case. As I have mentioned, I have no trouble running all of my other MTH Railking PS1 diesel loco's (all 12 of them) and having the horns, bells, and couplers open using the horn/whistle and bell buttons. I will take your advice and see if I can get one of the MTH transformers you have suggested, and "retire" the good old faithful Lionel RS-1.

Richie C: That is the interesting thing......the owners manual clearly shows the Lionel RS-1 is compatible with this loco. It fires the loco up, the protosound startup in neutral begins, the whistle starts blowing (on and off constantly), and then when the power is shut down and brought back up, the loco starts moving in the forward direction, as it should. The speed of the loco is controlled by the position of the handle on the transformer, all the while with the whistle constantly blowing.....very annoying!!!!!  I think D500 has hit it on the head, this transformer does not produce the required Sine Wave to send all of the messages to the circuit board. This is the first PS2 Railking loco I have in my collection, and it is the only Railking to have a problem with my transformer.

Thank you for all of your replies, and now I am on the look out for a new/second hand MTH Z-750 that wants to reside in Australia.

Peter.....Buco Australia.
