As shown by Member samparfitt, in his photo, this is why I like MTH / DCS over the Lionel Cab #1
MTH, will run Lionel Engines, (TMCC) Lionel is not engineered to run MTH equipment, YES, there are some minor limitations, but all is well on my layout.
Would not recommend this process for Lionel Legacy.
