Sorry to hear of you running issues with the MTH engine. I feel your pain.
My layout has been around over 40 years and has 27 Marx 1590 switches and is 027. I still have the running problems with most new to the layout engines. It always takes awhile to figure out what the cause is. I have most issues with 8 drive wheel engines, diesels, and 4 wheel leading trucks. Most recently was a Marx 333, 4-6-2 and the sliding power pick up. This was only on one of my to 333s. The one before this was a new Lionel 561, 0-8-0 switcher.
