Selection of a prototype - the Riverside Line

After looking at various possibilities I selected the Riverside and Beacon St. lines as my prototype. Basically the line starts out in the subway, surfaces on Beacon st. where it runs in a center reservation in the middle of the street to Cleveland Circle/Reservoir. There we have a loop for turning some cars and the main carbarn,. The line proceeds as private right of way through Newton to Riverside.

I chose this prototype for a couple of reasons. One is the variety of street running plus private right of way. Of course in real life the 2 lines (Riverside and Beacon st) are separate but I use modelers license to combine them, taking advantage of the co-located Reservoir and Cleveland Circle facilities. I also include a short section of street running (track in pavement) which the prototype does not have.
