This engine runs pretty well but at spots on the layout it slows and at times stops. Also, if I add 3 or more passenger cars it runs slower around the layout and will stop at two points. I've checked the voltage at those spots where it slows and stops and compared those readings to the areas of the layout where it runs OK...same voltage 17 or 16.9. What I'm not sure of is whether the TMCC signal plays a part in this running issue. No other TMCC/Legacy engine in my collection behaves this way.... I've greased and oiled per the manual. I've also put my hand over the engine in those areas where it slows down and that makes no difference. I'm not to interested in adding drops as most of the area of the track at issue is ballasted, but if that's what it takes OK... Help needed. I've had this engine for at least 5 years. It ran without issue when I purchased it. I rarely run it and I think it sat for at least 2 years before I put it on the track recently.
Info re: Voltage
Voltage at the Terminal of ZW-L = 18.1
Track voltage = 17.6, when Hudson powered down
Track voltage when Hudson powered up = 15.6
What I've noticed is the engine will run well with slow down in 2 spots, at switches but instead of stopping, it will make it through at max power. Anything less than maximum, it will stop in those areas. Also, I've started to switch out incandescent light bulbs in the passenger cars with LED bulbs. It runs well with LED lighted passenger car, but performance degrades as I add cars with incandescent bulbs...so, I'm going to replace all the bulbs.
If a video of what happens would be useful, please let me know and I'll attach one.
