Feeding wire through mast
Monday, August 23, 1999

The crew, boom truck, supply trailer and signal heads have all arrived at the Lower Grave Creek installation.  Before the heads can be lifted into place, wires must be run up the masts and the elbows installed.

Tom feeds the four signal head wires down the mast to Keith who is pulling the fish tape from below. 

Assembling signal heads Meanwhile Signal Supervisor Rich Gollen (in white shirt) and Dave Putman assemble the signal heads.
Lifting Signal Head A completed signal head is attached to a sling which is hung from the block on the boom truck.  Dave is gently raising the signal head up onto the mast.
Wiring into suspended head Tom runs the wires up into the signal head as it hangs from the boom truck.  Note how the wiring runs up out of the top of the elbow which Tom has attached to the mast. 

Barely visible against the black background are the color lenses for the signal.  Notice how the colors are in reverse order from the familiar and similar traffic light. 

Back side of signal head. The signal head swings around and we get a look at the back side.  There's a tiny light bulb behind each color lens but no reflector.  I asked Rich why there is no reflector and he said that it is against the law to have any reflective surface behind the lens.  A reflector or light colored surface behind the lens might allow sunlight or even the headlight of an approaching train to cause a signal to appear lit when it isn't. 
Heads face away from track Having finished the work at this location for today, Dave secures the block for the run up the line to the next installation.  The heads are left turned away from the track indicating they are not in service. 
Electrocode wiring  Rick works on wiring in the Electrocode unit inside a case.  John Posey, an independent signal contractor temporarily working on this project looks on.  This particular installation in Glendale involves the conversion of an existing tri-color signal to Electrocode 4 Plus equipment.  The relays and terminals in back are not typical of the new E-code cases but are for the original tri-color circuitry as well as a Safe Tran 3000 grade crossing installation.

Work like this will continue for the rest of the week in each of the five new equipment cases as well as any case being retained in this project.

Old E-code prepared for removal  This is an older Electrocode 3 installation at Leland that is being upgraded to new E-code 4 Plus equipment.  The boards and relays marked with yellow tape are to be removed and used elsewhere on CORP.
Programming an Electrocode Once the case is wired, it must be programmed.  Here Signal Engineer Alan is at work on an E-code conversion.  Yes, that's a laptop computer inside the case.

The Removal:  10 sets of semaphores are taken down.
