Remarks & Notes 
Operator Dick Herr is entering information on the Station Record of Train Movements at the 1938 vintage Union Switch & Signal Co. CTC machine governing train movements from Glen Loch through Coatesville, PA. This type of US&S panel was the technology that first enabled large scale centralization of dispatching or interlocking control. AT&SF, PRR, SAL, SP and UP had large such installations - some panels twice the size of Thorn's 120 lever capacity. Thorn was built in conjunction with the electrification of the PRR in this region. I held second trick here for a number of years, whereas Dick Herr was the first trick operator. Judging from the clock, I was likely working an overtime day as extra operator, owing to some mishap necessitating that a large volume of orders be handed up to passing traffic. The railroad here was still heavy freight territory at that time, with a healthy helping of GG-1s, E-44s and just about anything else under wires.
