New York City's Pennsylvania Station hosts colorlight signals that are suspended from the ceilings of the terminals. These signals manufactured by Union Switch and Signal Company of Swissvale Pennsylvania are only known to be used in a few terminals. The signals appear in the Union Switch and Signal Company's 1909; Electro-Pneumatic Catalogue Volume 2 and is not in any other US&S Catalog. The signals were installed prior to the terminals completion in 1910 have survived over 100 years, today several of the signals have been replaced by new Safetran signals. The Safetran signals are custom to fit the size and style of the older US&S style colorlights.
In 1909 these colorlight signals cost $64.00 for a 4 light and $74.00 for a 5 light.
