Reply to "Replacing Batteries with BCR's in MTH Locomotives"

Well first off the transition point started around the 2003/2004 time period.

Since I also have the 20-3045 and 20-3047 I know them to be a 5v system (8.4v battery). Also have the 20-3128 which is a 2.4v system (3v battery).

But overall the key is the battery charging port. If PS-2 and NO port them 5v system. All with a round port are also 5v systems. The 2.4v system engined have the rectangular port.
