During the month, I was commissioned by Chris (OGR member Lehigh Valley Railroad) to upgrade a few of his TMCC locomotives to ERR Cruise to get 100 speed steps.
One was a Lionel ALCO C-420, the second was a K-Line GP38-2, and the third was a GE U25B. The C-420 and GP38-2 had their DCDR's replaced with the Cruise M now, and are just awaiting new LED lighting. While waiting, I chose to get started on the U25B. However, unlike the first two engines, it had no DCDR for the Cruise M to replace. Here's how the electronics work under the hood:
Is this one of those engines that needs to have the whole electronics package replaced in order to get Cruise? Any help is, as always, appreciated.
