Title says it all, really. I'm absolutely delighted that the normal buffers and couplings that TGVs have between the power car and coaches also work as such in TSW.
Wow and by the way the TGV duplex in game isn't 15kv 16.7hz capable. DTG needs the Euroduplex version if you want to run this on the Riesa/Meißen-Coswig-Dresden-Bodenbach (Decin) Railway DLC. Remember you will be emergency braked by the PZB if you tried to run it on the Riesa-Dresden DLC
