I believe the County bought the right of way from the ole rail line that went to Hughesville just for this purpose.
Of course since then they took up the rails and sold the steel from them for a few bucks,then they allowed encroachment on the right of way and even parking lots built over it to the point where it is pretty much useless, between driveways and other uses.
Now that rail line went to Hughesvill and then on to Brandywine and then to Baltimore.
However there once was a line that went to Chesapeake Beach from District heights that could have been used some of it's roadbed is still existent,although its tracks are gone also. The two could have been tied together to possibly go to a station.
The expense would be great I am sure,but it could have been done,I suppose it never will be ,but elevated tracks could be run over Rt. 4 and taken into the Station in Suitland.
Nice to dream about ,but I dont expect to live to see it.
What I would oike to see is Gallant Green Rd. run into Brandywine and a junction over to Rt 5. so Southern Marylanders couldavoid Waldorf on their commute gallant Green Rd. dualised of course. the thing could run right alongside the existent railroad tracks, they wouldnt even have to survey the Route , Its already there.
