Hi Guys! looking for some suggestions over a problem that has got me non-plussed. I'm running an MTH Imperial PS/2 Big Boy and on sounding the bell or whistle the loco slows down noticeably. There is no shortage of track power because it doesn't affect my Y6B or even my FEF no. 844 running with a full set of heavyweight lighted passenger cars! Any suggestions gratefully received...

What kind of transformer are you using? The older PW transformers will definitely do this. Not so much on the modern transformers.
Hi, thanks for the quick reply! I'm using a custom made modern high output transformer, so it's definitely not the cause. I also wired in an MTH Z1000 for comparison and it was exactly the same with the other locos unaffected.
Well I can't answer that then. In theory these would all be the same sound boards I would think so I would expect the same results across any MTH same vintage locomotive.
You do not say how many amps you are pulling. I have noticed when I speed up the consist, or turn on smoke, bell or horn the amps being used goes up. If you are running at a high amp level, the whistle or horn might not be enough to trip the breaker; however, it might be sufficient that the transformer can not keep up with the amps. My Lionel 180 bricks have no issue with a load of trains that trips my MTH 1000 bricks.
I have that PS2 Imperial Big Boy and what you report is not present on my engine or any other. I run Z4K transformers and the results are the same with my ZW-L. I would start by doing your test on another layout. It seems like a locomotive issue. Do you have an MTH Tech close by that can put your board in his board tester?
