Dwarf Signals
A dwarf signal is used for controlling shunting movements. It can have any of the following aspects:
| Aspect | Meaning | |
|---|---|---|
| Stop | The signal must not be passed. | |
| Proceed with caution | The signal may be passed, but the track may be occupied by cars or another train. | |
| Signal cancelled | The signal may only be passed by the unit that has a permission to do shunting or track work. | |
A dwarf signal may also be placed in conjunction with a main signal. If the main signal shows any other aspect than Stop, the dwarf signal shows the Proceed with caution aspect.

Famous quotes containing the words dwarf and/or signals:
“A dwarf who brings a standard along with him to measure his own size—take my word, is a dwarf in more articles than one.”
—Laurence Sterne (1713–1768)
“The term preschooler signals another change in our expectations of children. While toddler refers to physical development, preschooler refers to a social and intellectual activity: going to school. That shift in emphasis is tremendously important, for it is at this age that we think of children as social creatures who can begin to solve problems.”
—Lawrence Kutner (20th century)
