Whammy= insurance carried by railroaders in the event of "run off" or disciplinary action.
Derailed= sometimes used to describe being "on the ground" or out of service.
Railroad Error= was used in demurrage and rates department/clerks to describe an error by the railroad in demurrage and storage charges or rates by the company.The customer would protest these mistakes and the saying was, "Charge it to 'railroad error'". It then came to mean ANY error by an employee and was used to express frustration over a mistake, usually by the employee uttering the phrase. You could be in the Yard or Freight office and someone would just blurt out to no one in particular, "RAILROAD ERROR!" Or, "We'll charge it to RAILROAD ERROR!" It was just a way to let off steam.
Go High= go beyond the switch stand, or clear it to line a train in.
Sign us (him, her, conductor, engineer, etc) ahead= to authorize movement via radio, flag, lantern, or green signal.
Shove out, or ahead= to shove a cut of cars, or tell an engineer to move his train.
Slam off= to run someone "Slam" off the right of way, fired with no recourse after investigation and arbitration.
Time Claim= claim for protected work covered by Union rules. A trainman comes into a shop, picks up a welder and welds a seam. The Machinist/Blacksmith/Carman that is protected by the shop agreement files a claim for a day's pay for the work done without authorization under the respective Union's rules. Railroads don't LIKE time claims (also called "time tickets" by some companies) and often themselves discourage non-covered people from doing craft work for fear of having to pay for it. This is why a rail buff should NOT get involved in railroad activities not only for safety reasons, but because it can cause the company trouble from the Unions in the form of claims for pay caused by work performed by outsiders. They are called "scabs" for a reason, and that includes non-employee railfans who want so BAD to get involved in railroad work. THEY think they are "helping", but they are not.
Kill the Blue flag= take up the blue flag on the repair track, OK to operate after track is clear, no repairs in progress, flag no long there.
