Do you use both outer rails as ground?  2R-3R engines have a limited power pickup.  Some of this sounds like DCS signal strength issue on your layout.  It could be drawbar, but if the engine still has power and making sounds then AC power is getting to the tender and so should the DCS signal.  Is the DCS DCC switch in the DCS position?  G

Thanks for your response triple G,

I don't have any isolated outer tracks on the main line of my layout, I know DCS can act up when there a isolated common.

Most of my layout I get 10-9 signal strength, there might be a couple of spots where I see 8-7, I am servicing the layout, so I will install some new drops.

Also, the track is not exactly pristine all the time, so I wonder if this could be a factor.

This is my only MTH steam engine, so I am not familiar with their quirks

The switch is in the DCS position, but I have read on the forum of this switch being defective

I have 15 others DCS, legacy, and TMCC diesels  that don't exhibit this unique hiccup

On maybe a related note

I have noticed the tether side drawbar post/connector swivel has lots play in it, is this desirable? or should I try to tighten up the screw??
