Now that I think about it, How is this possible? when the R142A were first delivered, After some of there motors were taken out because it was running to fast and they tested on the flushing line and it failed because it couldn't make it up the Steinway tube. why would they end removing a WHOLE motored truck from one of the 5 car sets? From ive heard they put most of the motors back but with limiting speed controls for the R188.
