There are still a few Type 1 interurbans in service today.
One of three that I saw when I was going out to St Vincents & the Beaverton branch of the portland clinic today.
(After several days of climbing the eastern side of the West Hills, dying repeatedly on the climb, I decided that since I was going to St Vincents as well as TPC I’d ride up to Lloyd Center, take the trolley under the West Hills, and proceed from there. Less riding (27 miles today) but more trolleys.)
