I'm thinking about upgrading my Lionel D&H RS-11 and SPSF SD40T-2 diesels from TMCC to DCS due to their TMCC operating capabilities being very bad as of late (they crawl to a stop or they stall on the same spots of track no matter what I do).
How much would it cost me to upgrade?
Does anyone know of any good model train mechanics that I could be referred to that could do the upgrades?
I'm okay with electrical wiring in general but I have a feeling doing something like this myself right away is a bit too advanced and I don't want to mess something up more than it already is.
Any kind or amount of information helps.
