Big Fat EMU

Look at what is quickly taking shape in Stadler's Altenrhein factory in Switzerland:

This is the huge double-deck, extra-wide, high-platform EMU for Moscow's airport train.  In a 25 kV version with an extra (temporary) pair of doors on the lower deck, these would make an ideal tool for gradually transforming Caltrain from a 20th century diesel commuter train into a fast, high-capacity level-boarding system fully compatible with high-speed rail.

Maybe if those trade sanctions kick in, they won't have anywhere to go?
