Back to Switch Stands

Switch machines are found in interlockings (aka Control Points), stations, some yards, and out on the mainline, where remote control of switches is required.

The GRS Model 5 series switch stands are some of the most common in North America. They come in 8 varieties (A through H) which support different features or were available in different time periods. The 5A through 5D were available from 1930 to 1988, and the 5E through 5H are available from 1988 to present, though they are currently sold by Alstom. Models with Internal Controllers are longer than those without Internal Controllers.

These switch machines are named _left and _right depending on which way the switch will go when thrown to the Reverse position. In Hammer, the Top-Down 2D view should show a small chevron that indicates the throw direction. Unlike hand-throw switch stands, there are _lh and _rh versions of this model (lefthand and righthand relative to the facing direction of the switch).

Sequence Description
idle Alias of idle_close
idle_close Machine stays in NORMAL position.
idle_open Machine stays in REVERSE position.
throw_open Machine moves from NORMAL to REVERSE. (1)
throw_close Machine moves from REVERSE to NORMAL. (1)
throw_open_fast Machine moves from NORMAL to REVERSE faster. (2)
throw_close_fast Machine moves from REVERSE to NORMAL faster. (2)

(1) The normal throw_open and throw_close sequences have 3 seconds of wind-up and spin-down at the start and the end... meaning the switch takes 9 seconds to throw. This is used for machines equipped with Low Voltage motors and are typically found out on the mainline or in remote locations where electricity is harder to come by.

(2) The throw_open_fast and throw_close_fast sequences do not have wind-up or spin-down periods and get right to moving... meaning the switch only takes about a second to throw. This is used for machines equipped with High Voltage motors and are typically found in yards or stations where electrical power is abundant.
