Bill,
We've already communicated off forum. Being raised in West Mifflin and still living in the South Hills, I remember it all-back in the day there were slag trains running to the dumps every 8 hour shift and as a kid it was a great show!!! The Union railroad was actually still dumping slag in the 70's but not at Browns Reserve. The trains came up the Mifflin branch underneath Route 885, along the old Continental Can plant and curved right towards the back of the plant and dumped over the hill. For the life of me, I can't remember the name of that dump site. This was right about the time that the county was extending the main Allegheny County Airport runway over Route 885 and the Union railroad tracks near Mifflin yard where the URR exchanged cars with the Montour RR. Once the runway extension was completed the dumping stopped.
Hot Water,
The term yunz is just a local Western Pa slang contraction for the words you uns, just as in the South the term ya'll means you all. Southern guys, hope I got that right.
