Reply to "How long can a postwar Lionel 252 crossing gate be activated without overheating or damaging it?"

I had a similar concern with overheating in relation to another Postwar Lionel accessory that also uses a solenoid namely a 151  semaphore signal. I had a couple of times where the 151 signal did overheat and I came up with a different solution than what has already been mentioned. I purchased off Ebay a temperature sensing shutoff switch and attached this special switch to the underside of the signal and up next to the base of the solenoid. The temperature sensing switches were available with a whole range of available trigger shutoff points. I picked one that sounded logical to me and that was it. When triggered the signal shutoff as desired and after a good cool down time the signal came back on again automatically. These switches were from China and very inexpensive.
