Hi You might try setting one of the engines to run in reverse- this is in the programming area for the decoder. In an NCE PowerCab, this is in the setup area, in a LokProgrammer, it is in the driving characteristics area. The CV is 29 in all cases. If you read the CV29 value and add 1, it should reverse the sense of direction. See the NCE website, TCS website or other sources for the coding of CV29.
