There is a good summary of past RR stations (with GPS locations) in Shippensburg:

It says the joint Reading/Western Maryland station was used as a library before it was demolished, but gives no dates. The Cumberland Valley RR became the PRR, its later station was about a block away.
The current Shippensburg Public Library appears to be nearby on W.King St, in the same general vicinity, but was not previously RR related from what I can tell.
