371 was led by an ex-Airport Silverliner III today. It passed 386 somewhere between Trevose and Somerton. 386 was also lead by an ex-Airport Silverliner III. The two cars were 235 and 237, but now I don't recall which was which.
Both trains had an ex-Reading Silverliner II as the third of three cars - 9012 on one, and 9013 on the other. Silverliner III 221 was the middle car on 371. An ex-Pennsy Silverliner II (not 269 or any of the other interesting ones) was the middle car on 386.
(It is not usually possible to observe from one train the car numbers on a passing train. I was not on 371 at the time. I had taken the Comet cars West Trenton express, 6374, from Center City to Somerton, with the intention of taking 371 back to Bethayres. Since the express was running a little late, I didn't want to chance the 7-minute layover in Trevose, where I'd have to wait for the long express train to clear the station before I could cross the tracks on foot. So I settled for the longer wait at Somerton on a springlike late afternoon. As a bonus, I got to watch 386 come through.)
Soon you will need to be in your 60s in order to remember the 60s.
