Project 0722, Harmon HXP Crossing Processor
Gathering Materials-
I have a friend with the railroad who saves me somethings when he can throw them out. The other day he threw out a old Harmon HXP, a CTU1, and a Aux crossing relay box. All seemed to be there except for the standby HXP unit.
Plan-
Was to try and get the units wired and too the point you can flip a switch to activate the system
Operation-
Got the unit powered on and running but there are errors and the unit is missing the island card. Went back to my friend and asked if he had a island card for it and she said no thats the problem these only worked 50% of the time and you can not find parts for them.
Final-
The unit is wired as said to be in the diagrams but operations are not working, it must be configured to the right freq.

The HXP is the top unit with the LCD display, below that is the CTU (Control Transfer Unit). The battery bank is under the CTU and powers the unit. We are missing the island card and the standby HXP.
