Semaphore Signals

September 6, 2010

Ray asks readers:

"Does anyone know of another method of contoling Semaphore Signals? I use RR&Co 7 Gold with Digitrax Chief to control my DCC system. I use SE8c controllers for my signal lights. I chose not to use the SE8c for the semaphores because I can't get the Tortoise drives under my middle and top track levels and clear the trains below. I am using the SMC4 boards with RC mini servos that tuck under easily. The SMC4 operates the semaphores with (3) addresses and 'throw commands only'. I have had to use a (3) aspect signal for the first two addresses and a (2) aspect signal for the third. However,the SMC4 works only upon an actuation signal with no memory. This causes some problems. Does anyone know of another method of contoling Semaphore Signals, or do they know of a smaller stall motor drive to replace the toroise?
