<p>I was wondering if there are any buses/trains that go from Pittsburgh to Allentown (beside holiday buses)</p>
<p>Look at Greyhound - they have busses going to Allentown. Megabus doesn’t stop in Allentown but does in other PA cities (which depending on where you are ultimately going may be an alternative). No Amtrak service to Allentown, but you can get to Phili.</p>
