I've posted this in the DCC forum, but thought it might be useful here too.
I purchased a Bachmann 35-303, 37 305 in BR blue. Tested it with the Bachmann Plux22 decoder 36-570 and it had a problem with the marker and tail lights on both ends being lit all at once, with no ability to operate them independently. There is a note in the Class 37 manual that when using 36-570 instead of 36-570A, three CVs need altering, but one has been misprinted; CV123 should be 124. All other CVs and their values are as written and reprogramming them allows the lights to work correctly with the 36-570 decoder.
This was my first of the revamped Bachmann 37s and I'm very happy with it, especially as the detachable nose front area fits perfectly, which I found to be a weak point on previous versions.
