I just checked, and there are no other engines that have the same 4-digit cab number in my command base. Bummer, that sounded like a good possibility.

any way I was trying to pin point a issue with a IR feather and swapped tenders with a S-3 and UP Challenger. When the Challenger tender went over the track with the S-3 attached it uploaded Milwaukee Road #261 S-3 into slot Eng61. When the S-3 tender went over either the challenger on Eng 85 I saw the fule and water level updated also in each instance the action was played to the correct locomotive that actually went over.
Clearly my diesel can't swap tenders. 
Also, what you describe doesn't sound like the RCMC had the data. If putting the S-3 tender on the 4-4-0 caused it to upload the S-3 data into the base, it sure sounds like the tender had the data.
