This picture was taken in the Spring of 1973 on a TMS weekend trip to Lisbon. The location is Martim Moniz where the track layout is quite different now with the Graca trams terminating in the opposite corner of the square.
Merlyn Bacon is leaning out of the window and I think Bob Tebb is standing on the platform.

I hope to publish some more Crich pictures later this week.
