Posted by randyo on Thu Jan 23 03:53:19 2025, in response to Flushing Line Automation 1958, posted by Q65A on Wed Jan 22 12:07:50 2025. Although the photo is B/W you will note that the signal plates on the home ball are 2 different colors. On the original IRT signals, the automatic signals had black numbers on a while plate and interlocking signals had white numbers on a red plate. Old IRT interlocking signals only had the lever number but not the chaining number. IND and postwar signals carried both the chaining number and the lever (or button) number. The signals on the Flushing line had the chaining number black on white and the lever number white on red. Subsequent IRT signal installations had both numbers black on white and eventually the signals on the Flushing Line were changed to match. |
