The low stand 22-E is for yard, ladder and busy switch turn-outs, where trains often run through switches. The 22-EH is constructed of identical base housing and operating parts, but features a high mast and target, providing increased visibility where needed.
- Can be trailed or thrown manually
- When a train runs through the switch, switch points are opened by wheel flanges, and then throw is completed automatically
- During automatic trailing, the target rotates so that the switch point position is indicated, while the hand lever remains stationary
