Citadis Spirit is essentialy a mix of a Regio-Citadis and Citadis-Dualis with an Alstom Metropolis automated control system. This isn't a train that has technologies out of Alstoms reach... Yet they have problems making doors work properly! They have trains rolling in Russia so winter isn't and shouldn't be a problem ... Maybe it's not Alstom that we should blame but rather RTG.

Citadis is a line of trains not a model of train. A good way of looking at is is Citadis to Alstom is what Chevrolet is to GM. When Chevrolet comes out with a new model of car, everyone expects there to be issues at the beginning with it (even if it is similar to a different one), and it takes a bit to resolve the issues.

Not just that, but North America uses different standard for wire and metal gauges than Europe and Asia. You can't just substitute the closest equivalent as when folded/bundled/wrapped, the differences compound and the pieces may not fit. I once worked on a project where the contract manufacturer substituted a similar (but slightly thicker) metric gauge sheet metal for the gauge specified in the design (without telling us) and it caused a major problem as the fans didn't quite fit properly in the case and started seizing.
As a result, it is easier to redesign everything from the ground up. I know someone who did some preliminary design work on the Citadis Spirit, and he said it shares little with the other Citadis trains for those reasons.
