track power controller 300

[phillyreading]

Have you tried cleaning the track and wheels of the loco and tender being that it is post war you may have a dirt build up that is causing an overload for power consumtion.  Take a flat tip screwdriver and hold it on the wheels as you turn them and see if any dirt falls off, if so you have a major dirt build up!!!

I had a problem with my post war tender's whistle blowing almost all the time until I cleaned the wheels off(both center wheels and outer wheels), after that no more ramdon whistle blowing.

Is the tpc 300 more sensitive to shorts?  Because I never had problems when I used my post-war transformer.

Yes. The circuit breaker in the TPC is going to be much more sensitive to shorts than the PW transformer you were using.  The fact that the breaker does trip is indication somethings wrong; you'll need to troubleshoot that per the previous post.

I use a TPC 400 having a 20 amp breaker.  If I have a derail the 15 amp breakers on my PH's trip rather than the TPC's   With a postwar engine without any kind of connection to the tender you should be able to run the engine without the tender to see if the tender is the cause.  I've seen occasions where the roller on an item is wide enough to short on some switches or operating tracks.

I am having problems running my post-war coal tenders in conventional mode on the tpc 300.  My post-war steam engine runs only a short distance then shuts down and I believe the cause is a short circuit in the tender. Is the tpc 300 more sensitive to shorts?  Because I never had problems when I used my post-war transformer. Is this a common problem with the tenders and the tpc 300?  Could the pickup rollers be touching the trucks cause this problem?
