Greetings from the Black Hills in South Dakota. Been following your CTC machine build for a while now, very nice and am very impressed with the professional approach in design and execution. I am in process of constructing a CTC machine similar in complexity but for my smaller HO gauge layout. Over the last two years I have managed to acquire quite a few original Western Electric components, so much so I could construct a relay based machine but am mainly focused on indicators and switches which I have enough of and can move forward.
I have a planned trip to Boston in October and would be interested to know if you have visiting hours. Would like to visit to see the A&O and perhaps compare notes on CTC machines. BTW, my background is in producing mainly science shows for National Geographic and Discovery Channels along with a variety of other supporting services. Would be happy to contribute what I can to support the A&O operation.
