BGAS Position Light Signals - MagnumMacKivler/trakpak3 GitHub Wiki
Position Light Signals were used by the Pennsylvania Railroad and its associates, and operate by mimicking the motion of a semaphore. Most of the lenses were a fog-cutting lemon yellow, but later on, some were fitted with red lenses in the horizontal position, and others were colorized similar to B&O's CPL signals.

The model name describes the colors the signals can display; r for "Red" (horizontal), l for "Lunar" (Down Diagonal), y for "Yellow" (Up Diagonal), and g for "Green" (Vertical). If a model can't display a color (e.g. ryg.mdl attempting to show Lunar), it will default to Off. In addition, signals can be "Red Eye" (the horizontal position has red lenses) or Colorized.
Bodygroups:
| Option | Aspect (BG1) |
|---|---|
| 0 | Off |
| 1 | Horizontal (Red) |
| 2 | Down Diagonal (Lunar) |
| 3 | Up Diagonal (Yellow) |
| 4 | Flashing Up Diagonal (Flashing Yellow) |
| 5 | Vertical (Green) |

The model name describes the speeds the signal will be capable of displaying: m for Medium (and Limited), s for Slow, and r for Restricted. If a model can't display a color (e.g. ms.mdl attempting to show Restricted), it will default to Off. There is also a single variety for showing Stop and Proceed. In addition, models can be Colorized.
Bodygroups:
| Option | Aspect (BG1) | Target (BG2) |
|---|---|---|
| 0 | Off | Clipped Circle ("Standard") |
| 1 | Flashing Vertical (Limited) | Full Circle |
| 2 | Vertical (Medium) | Vertical (Medium/Limited Only) |
| 3 | Flashing Up Diagonal (Medium Approach Only) | Up Diagonal (Slow Only) |
| 4 | Up Diagonal (Slow) | Down Diagonal (Restricted Only) |
| 5 | Down Diagonal (Restricted) | None |
| 6 | Single (Stop and Proceed) |
Dwarf Signals (PL4)

All PL4 signal models behave identically.
Bodygroups and Skins
| Option | Aspect (BG1) | Skin |

Pedestal Signals (PL5)

models/trakpak3_us/signals/positionlight/pl5_full_redeye.mdl
Pedestal signals come in regular and red-eye variants. Unlike the PL3/4 models, the PL5's bodygroups correspond to specific signal rules in the PRR/PC/CR rulebooks.
Bodygroups and Skins
| Option | Rule (BG1) | Housing Shape (BG2) | Skin |
|---|---|---|---|
| 0 | Off | Rounded | White Lenses |
| 1 | Stop | Square | Red Lenses |
| 2 | Stop and Proceed | ||

Chicago Union Station Signals (Domino)
models/trakpak3_us/signals/positionlight/domino.mdl
There is only one model for the low-clearance "Domino" signal, but similar to the PL5 above, the bodygroups correspond with specific rules.

Northumberland Signals (Teardrop)
models/trakpak3_us/signals/positionlight/teardrop_full.mdl
There is only one model for the fully-fledged low-clearance "Teardrop" model, but similar to the PL5 above, the bodygroups correspond with specific rules. Unlike the Domino signal, this model's bodygroups line up with those of the PL5, except No. 6 (Slow Clear), which this signal cannot display.

| 0 | Off |
| 1 | Stop |
