Which term refers to a switch defined by a yellow switch stand, where trailing point moves may pass through the switch without hand alignment unless otherwise specified?

• A. Slow Speed
• B. Automatic Safety Switch
• C. Crossover
• D. Derail

Answer: (A)

A slow speed turnout is identified by a yellow switch stand and is designed so trailing-point moves may pass through the switch without the points being manually aligned, unless a specific instruction says otherwise. This setup lets a train go through at reduced speed with caution, recognizing that the switch may not be set for the route ahead unless targeted alignment is performed. The yellow stand serves as a clear caution that the switch operates differently from normal interlocked or hand-thrown turnouts, requiring slower movement and readiness to stop or adjust as needed. This differs from a crossover, which is a pair of turnouts that let trains move between parallel tracks; a derail, which is a safety device used to prevent movement on a track; and an automatic safety switch, which operates automatically and is interlocked.
