Re: NNG: Light rail testing

The DIA line will be heavy rail commuter operation with the most likely equipment being electric multiple unit. The Gold Line, which will follow the BNSF Golden line (ex narrow gauge) will also be electric multiple unit heavy rail as will be the Thornton Northglen line. That lines follows the UP Dent branch.
The line to Westminster with eventual extensions to Boulder and Longmont will probably be diesel multiple unit heavy rail.
The only lmajor ight rail additions after the completion of the West Corrider will be an extension of the Parker Road branch up I-225 to meet the DIA line. The Southwest Corrider will be extended to Lucent BLvd. on C470 and the Southeast Corrider will be extended about a mile.
