The What do the Marker Lights mean?
Before the advent of the large destination boards now seen on the front of the current trains on the system, marker lights were used to identify what line the train was running on.
Each marker light was a double made up of a red and white lens, these marker lights became a feature of the front of the cars. The light configurations shown below are shown looking at the front of the train. The drivers cab is on the right hand side.
Below is a description and example of each line.
