A recent discussion under MTA - NYC Subway prompted a new subject: the nomenclature -- industry and trade jargon -- used on different properties to denote the same thing. The example that came to light was the practice of filling gaps in the schedule resulting from service interruptions by having the first trains run nonstop to close the gap. According to FanRailer, these trains are called battery runs in New York. This is done all over by various properties; what do they call them in Boston, Philadelphia, Chicago, etc.? Another example is that what is called layover time in the East is apparently called "spot time" in Los Angeles. Another example would be the different names for cabooses: cabin cars, way cars, hacks, (vans in Canada). Around the country, how many different names are there for the same operation?
