Siemens just released their new G1 subway trains into revenue service in Nuremberg, Germany. Siemens has already a big footprint in the rail market in North America. So it can be assumed that for the RFQ process for new TTC subway trains they will bid with their new G1 type trains. I like the colour scheme of the Nuremberg subway as it fits well the TTC scheme. Also, it’s a beautiful design of a metro train. See for yourself and all your opinions are most welcome!
The metros that Bbr Seimens and Alstom build are all custom products and not off the shelf like buses so in the end it doesnt really matter who the supplier is. The only real differentiators between them are the chassis that the body sits on and the internals. If you want a good looking train, start by hiring a good design team for the body. Obviously whoever specified the shape and finish of the TRs lack any artistic style.
