Here's a neat photo from the Chronicle Herald Archives showing the new trolleybuses at the corner of Spring Garden and Barrington on March 1, 1949.
I find it interesting that all the cobblestones and rails are still in place, I imagine due to the rail system having just been taken out of service, or still running with some overlap. Definitely a photo which illustrates some transition between services, in any case.
