Back in the day my hometown was served by 5 class 1 railroads. The Erie being one of them.
These two Steamers were long before my time but both unique in their own right.
One of the other 5-roads was the P&LE. In the day the P&LE pulled the "Steel King" passenger train three times a day from Pittsburgh to the P&LE's terminus point in my hometown. There they handed off their consist to the Erie with an additional Erie consist to continue on to Cleveland. This is were the Erie used Alco RS-2's to pull the consist. As I said three times a day in both directions. The RS-2 was fitted with call and marker lights welded to small structural steel brackets. This train to Cleveland is how I got to see the Indian's play ball. Unfortunately none of our toy train makers make a RS-2 so this RS-3 has to be close enough.
Than a somewhat standard freight diesel. This is probably similar to the power pulling a hot metal car through town when the load was dumped at a road crossing. Wish Rich Melvin would jump in here with the details of that event.
