Service end date?
According to this article, which is potentially unreliable, a stub of the Interstate Express survived on the CNJ between Jim Thorpe and Wilkes-Barre up through 1963. I do find such a train in my June 1963 Official Guide, Nos. 301/306, but I haven't found anything further on the subject. It's a bizarre outlier whatever it is, since there wasn't any other passenger service on the CNJ between Jim Thorpe and Allentown. Mackensen (talk) 23:18, 29 June 2013 (UTC)
There's an article in Bee Line which might help; see http://www.readingrailroad.org/reference/ref_beeline.shtml. The article is "Nocturnal Interstate Express, Train 301" from Issue 4, 1990. Apparently the Bee Line is accessible at the museum in Strasburg; it doesn't appear that it's archived in any libraries. Mackensen (talk) 23:50, 29 June 2013 (UTC)
