Chuck,

Three block protection.  The signal cards I used are able to put out four
conditions (two bits).   They were designed for modern signals: red, yellow,
green, & dark.  I modified them to light the DL&W red-yellow red-green
signal heads.

Dear Frank,

I'm curious, do your trains have three- or four-block protection?  Put
another way, do the signals have three or four different aspects that can be
displayed?  Silly question: can the trains run a red signal?  The reason why
I ask is that I grew up near the tracks in South Orange, NJ and the
Morristown Line used a four-aspect system (green, yellow, green and yellow,
and red) system with short (roughly half-mile) blocks.  I don't know if the
DL&W utilized that system universally, as typically blocks were two miles in
length once you got outside of the congested commuter zone.

Chuck
