The 9276 sure has been there a long time.
When you say went out of service do you mean it had trouble and died like the NJT SW up at Rt. 73? Did they take to 9276 to JT in Philly for repair?
I like your before and after photos. I noticed the new one is different with a big square box on top of the hood and big numbers. Its not real original but still a nice looking switcher.
