curse of the railroad gods

I am cursed i was very excited to goto NEPA freethinker meeting that started at 3pm today but then at 12:14pm i was called into work to go look at false activation of crossing. allot of times calls for crossings is as simple as reseting cards similar to pci card in a computer. well i thought this will be short call so i left as soon as i got to call(most times i take my time to get ready since i get paid by the hour from time of call). its about a 40 min drive so i was sure i could get there fix it and be back by 2:15 so i rush there getting there a 12:45 and look at the sydt a card on the box controlling flasher light activation at crossing. the box is called a phase motion detector and has 2 reading one is rx and the other is phase angle it works by phase and rx dropping raising to determine direction and speed of the train. the great thing with this system is that it tell if the train is stopped or backing away from the crossing and will rise the gate to let traffic move if the train no threat to the crossing. the RX and phase of every crossing is always some what different crossing to crossing but at this crossing normal range is 85/74 that is rx over phase, when i checked sydt card i had a 85/107. 107 is very high and I knew just what it was it was an open shunt wire. (shunts are the limits of the crossing protection, the limits are often a few hundred feet up tracks depending on track speed you need longer starts for areas with faster track speeds. well anyway back to troubles at this crossing. So i headed to limits where shunt wire where and they looked fine but i replaced them anyway and i walked to the other and still the light where going and bells where ringing witch pissed me off a lot since this was taking way longer then i had expected it to be in the first place replacing the shunt wires took some time about 2o to 30 to punch out the old chicken heads and knock in the new ones and it was already 2:30 and even if i got done just then i would be late for the meeting after i got home and took a shower and went to wilkesbarre where the meeting would be held. So i just shunted the track by the crossing to see if the reading would change with a shunt near the crossing witch it should since the closer you shunt the track to the crossing the lower the reading. The shunt produced no change so i shunted it at the surge arrester still no effect and then i shunted the pmd box, still nothing. Turns out now i did not know what that 107 phase reading was, the reading was caused by pmd being dead most likely taken a lightning hit burning up some electrical circuit. Since my pmd box was dead i had to have co worker called into work to bring me a part from Lockhaven over an hour. Make it short i didn’t see the new working box till about 5:30. skipping over a lot of details but after i got everything rewired and tested and as i was wrapping up got another call from the trouble desk turns out another crossing was activated. To finish i didn’t get home till after 10 pm.
