its just about identical..same design company. The difference is in the modernization of systems.


The two systems are far from identical. Track gauge different, car length different, maximum train length different, signaling and train control different, third rail voltage different, performance profiles different.

Yes a number of contractors from engineering to construction to rolling stock worked on both but the basic specifications they designed and built to were different.

in the future another line is going to open that is the first suburb to suburb line in Maryland outside the beltway.

Light rail; design, build, operate franchise contract with the Maryland Transit Administration. Not part of Metrorail.
