MBTA cannot do it because the current rolling stock varies. On the Red line they have 2 different types with varying measurements and the CRRC will make it 3. Orange has 2, Green has 3, and eventually 4. Until all of the rolling stock has the same measurements they cannot even consider platform gates.

Old orange line cars have basically been unofficially retired, green line type 10s will replace the entire fleet, new red line cars will eventually be a full fleet replacement. Blue line you could do it now. Point is, PSDs should be part of the respective fleet replacement projects IMHO.
