How can I tell if the signal is automatic or an interlocking one?

Does anyone (besides me) remember the lower quadrant semaphores on the Jerome Ave and New Lots lines???

These signals may all be gone by now.There was one at Fisk that was removed from service in the last year. There may be one or two at E180th which are in the process of being replaced now.
