Here are a couple of photos of MP-41s, LIRR's first electric cars. They were around until the early 1950s.
The LIRR BRT connection was referred to as the Chestnut st connection. It was in East New York and you can still see a few girders in the trackway on the BMT Jamaica line near Norwood Ave where this connection once came in. Here is the connection at the BRT
and here is the other end at the LIRR
