Temporary Block Station (TBS) is defined as which of the following?

• A. A sign posted on a track indicating speed restrictions.
• B. A building where timetable books are stored.
• C. A manned station that is established by Bulletin Order of Form D to control the movement of trains.
• D. A device controlling interlocking signals.

Answer: (C)

A Temporary Block Station is a staffed, temporary point along the track where a work or traffic control situation requires a controlled movement while a normal block station isn’t in place. It is set up by a Bulletin Order of Form D, which gives the on‑duty person authority to supervise and issue train movements within that block. This means trains enter and proceed under the specific instructions in the order, with the attendant on duty ensuring the block limits are followed and trains do not conflictingly occupy the same section. It’s different from a sign that only limits speed, a building that just stores timetable books, or a device that controls interlocking signals—the TBS is a live, manned authority point created to manage train movement safely in a temporary setup.
