Multi-Aspect Signals NewGRF

Features

• This GRF includes 4-aspect signal graphics (red, yellow, double-yellow, green) for the block signal, path and one-way path signal types.
• Two different styles of block signal graphics are included. Use the GRF parameter to select which to use.
• Custom signal styles: shunt, banner repeater and combined normal/shunt, this is enabled by a GRF parameter.
• Two different heights of path signal graphics are included. Use the GRF parameter to select which to use, or whether it depends on the available vertical clearance. Short path signals requires that block signals are using traditional graphics.

Requirements

• This GRF requires a non-standard version of OpenTTD which supports the signal graphics and multi-aspect features such as JGR's patchpack v0.43.0 or later.
• Realistic braking must be enabled for multi-aspect signalling to be enabled.
• Custom signal styles require a non-standard version of OpenTTD which supports this feature such as JGR's patchpack v0.48.0 or later.
• Signal height depending on available vertical clearance requires a non-standard version of OpenTTD which supports this feature such as JGR's patchpack v0.53.0 or later.

Things not included

• This GRF does not include semaphores or any type of pre-signal.
