The newest cars on the "T" built by CRRC creep into North Station which has seen massive changes over the years, once elevated pre 1975 and more recently merged with the Green Line in 2004.
The MBTA is very dear to me. The first trains I ever rode as a toddle to teenager were those of the "T" Here is a collection of MBTA Subway and trolley I have found on RP from the 60's thru today.
