There were two Electroliners, (btw, they were 4 unit articulateds, not 5) 
both equipped with poles and third rail shoes (the third rail was for 
running on the Chicago "El" tracks).
When the North Shore closed down in 1963, they went to Philadelphia where
the poles were removed, as well as the steps (for use with the "high level"
platforms) where they became the "Liberty Liners".  
When they were retired, one went to a museum in PA, (the one you've seen), 
he
other went to The Illinois RR Museum at Union IL, where it has been restored
to it's original configuration.
I was unable to ride them when they were in Revenue service (the North Shore
ceased operations on my 16th. birthday), but I have ridden the one at Union.
(The Electroliners hold a special place in my heart, as I model the North
Shore in HO, and have a brass model of one)
They were the FASTEST interurbans in the world, and were in fact the 
prototypes for the Japanese "Bullet" trains.
