Cohoes Signal

Postby Mdudek » Wed Feb 07, 2018 9:20 am

On the Colonie Main in Cohoes, there is a signal near Mohawk Paper that is always lit (yellow over red unless a train is nearby). I was wondering what the significance of that signal was. I thought the lower light had something to do with a diverging route, but the Green Island branch is long gone. Also, it is one of the only signals that isn't approach lit.

Thanks for any info!

Yellow over red = approach, which tells a train to be prepared to stop at the next signal. This would be the default for an automatic signal when the next signal is an interlocking or controlled point that is left at stop until manually cleared for a train to pass.

This signal is the last automatic block before the absolute signal at CPO5 (formerly NG Cabin). This is capable of 3 indications, Clear, Approach, and Restricting. In D&H signal practice, a signal with staggered aspects is the last automatic block signal before an absolute.
