At this time Rapido Trains has chosen to not use the Rapido-TCS decoder for the upcoming Alco PA/PB locomotive. While both companies still look forward to working together these PA/PB locomotive will not ship with a TCS manufactured decoder.
TCS will be releasing a custom decoder preset to be a perfect fit in the Rapido PA/PB. Pre-Orders will be opening for this decoder soon so check back here for additional details.
More information - including road names, pricing, and pre-order details - can be found on Rapido's website.
