Every Friday evening, I post the subway service changes for the weekend ahead, and although many of the changes are self-explanatory, some of the phrases are rather technical. With the help of a regular SAS reader, I’ve put together the beginnings of a glossary to define some of the more obscure terms. This weekend’s changes follow.
Track Chip Out — Using chip and jackhammers to chip out the old concrete roadbed and excavate the old roadbed around ties and rails leaving just the track assembly itself.
Concrete Pour — Pouring a new concrete roadbed. It takes approx 24-48 hours for a new concrete roadbed to cure to full strength after it is poured. Think of it in terms of pouring a new foundation for a building in concrete forms.
Track Panel Installation — Track panels are just that: panels of pre-assembled track, usually 39 feet long. The only thing that has to be added is the third rail and electrical connections. It’s comprised of two running rails attached to the ties using “E” clips — so called because they are shaped like a lower case “e” and a trackman can use a hammer to just knock em in or off the tie and rail — instead of spikes and weighs approximately 8-9.5 tons, hence why only one type of crane on a work train can lift it. The crane is a 10-ton mantis which pivots on a base at one end of a crane car. The other end has a cradle for the crane boom to rest in. Once the panel is dropped or lowered into place, the third rail chairs and rail are installed and electrical connections are made for power and ground. Generally, the rail is nowadays welded, but it can also be bolted with rail joiners to the section previously put down. Track panels on elevated structure are usually bolted whereas on grade or ground or subway, they’re welded.

Are there plans to make the glossary a separate file that could be linked to? The glossary’s a great idea. Now, if only the MTA can use those technical phrases in its printed service notices instead of vague and elementary-school phrases like “We are performing track work.” (Well, not elementary level, but they are too simplified as if we are being talked down to.)
I would also like to be able to eventually use it in my mobile application, if you don’t mind. I won’t forget to attribute it to you and your regular reader, if he or she wants to be identified.
