Dual gauge
Railway track with more than two rails
Dual gauge
A dual gauge railroad track has three or four rails, allowing vehicles of two track gauges to run on it. Signalling and sidings are more expensive to install on dual gauge tracks than on two single gauge tracks. Dual gauge is used when there is not enough room for two single tracks or when tracks of two different gauges meet in marshalling yards or train stations.
