Temporary track speed restrictions are designated by dispatcher message or Form EC-1 and specify which of the following?

• A. Authorized speed.
• B. Limits of the restriction.
• C. If wayside signs are displayed.
• D. Authorized speed, limits of the restriction, and if wayside signs are displayed.

Answer: (D)

Temporary track speed restrictions are issued to protect crews and equipment when track conditions aren’t suitable for normal operations. A dispatcher message or Form EC-1 that designates a TSR must spell out three things: the authorized speed to be used within the restricted area, the limits of the restriction—where it starts and ends (and for how long), and whether wayside signs are displayed along the track to indicate the restriction. Knowing all three ensures you operate at the correct speed, understand exactly where the restriction applies, and know whether you should rely on on-track signs for confirmation. If signs are present, they provide a visual reference in addition to the written directive; if not, you rely on the limits given in the dispatcher message or EC-1.
