The front and rear axle wheels are semi seized so I need a new 3 axle chassis for this engine,unless someone can
teel me how to get them unseized. The engine works perfectly otherwise and has never been in a wet location or abused.

Do the wheels look like they may have zinc pest and have swollen? With a wheel puller or two flat tip screw drivers you may have to lift wheel off chassis.
Best to remove all linkage and find out which wheel axle has binding.
OR, does this model have the piston type smoke unit. If so, the piston may have seized in housing. Disconnect linkage from drive gear, and see if that frees up axles. IF so, take smoke unit off engine, get piston out, and polish it down, both piston in internal chamber to get free movement. Not too much it is an air piston. G
Thanks for the info. I noticed, after removing the linkages' that the wheels one side of both the front and 3rd axles were very close to the body of the chassis. I inserted the blade of a putty knife between the chassis and the wheel and that allowed both axels to move freely. Thank you very much for your help.

Hi, I'm new to the forum, and I'm wondering if you can help me. I have a railing Hudson that doesn't run. It has the QSI DCRU and no protosounds. I've tried contacting QSI but have not received any reply. Can you fix this engine, and while you are at it add a QSI 3000 sound board? Also, is this cost prohibitive? Thanks for your help,

Yes, Is this MTH engine? My e-mail in profile so you can contact me. QSI O is no longer and the QSI product line is obsolete for O. I do have some boards, and I can repair the DCRU or replace it. Or it can be upgraded to PS-1 if you want to keep it conventional. G
