Has RTD decided upon what type of EMUs to buy yet?
Specifically meaning FRA compliant, or alternate FRA compliiant?
I ask because EMU rolling stock varies significantly.
Examples of FRA compliant EMUs:
New York's MTA LIRR and Metro North M7s
CDOT's (Metro North) M8s
Philadelphia's SEPTA latest Silverliner Vs.
Some non-FRA EMUs (possible alternate FRA compliant in the near future)
Stadler GTW
Stadler Flirt
Stadler DOSTO
Bombardier Talent 2
Siemens Desiro Classic
I believe the lighter non FRA comliant trains look much better.....
Of course, being FRA compliant is a requirement in a rail corridor owned by freight railroad companies. But it appears RTD is buying significant portions of the BNSF corridors, which should make it easier to run "alternate" FRA compliant EMUs. Many of the European EMUs have low floors, requiring platform just 24 inches above top of rail, vs 51 inches for FRA compliant trains.....
Also, there is a FRA report soon to be released (by late March or April) on how to make many of the European non compliant trains meet future "alternate" FRA regulations. Which should make it possible to run "alternate" compliant trains with FRA compliant trains (specifically freight trains) ....
So, it may be a good idea for RTD to wait and see that report before ordering any EMUs. Also, many of the European EMUs have DMUs versions too, which will make the different powered trains look more alike.....
