2019 Proposed Updates to Special Trackwork Elements

Rail operators who report annually to the National Transit Database (NTD) file the A-20 form, which currently collects the following special track work categories: Half grand union, single turnout, single crossover, and double diamond crossover.

On April 9, 2019, FTA issued a Federal Register Notice which, among other proposed changes, recommends the following modifications to this form: 

(1) remove half grand union

(2) rename double diamond crossover to double crossover, and

(3) include three new special track work categories: Slip switch, lapped turnout, and rail crossing.

Proposed modifications and definitions for 2019 special trackwork categories are found in the attached document.
