Type 1 is old school railroad track construction with conventional cross ties. Type 2/modified Type 2 track utilizes short ties embedded in concrete with an trough that runs down the middle for irrigation. This is typical of all IND main line track, and dual contract track construction originally found only in subway stations, and a few elevated locations.Modified Type 2 is the same, as Type 1, with exception to a full length tie at every third rail rail surface insulator. Modified Type 2 is the most prevalent of Type 2 track construction used by NYCT where subway Type 1 track has been replaced. When the IND was being built, it was decided to use Type 2 track construction throughout the main line system. Exceptions would be on non revenue tracks that could use Type 1. |
