Comet (railcar)
 The Comet railcar is a class of locomotive-hauled railcars that was first designed in the late 1960s by Pullman-Standard as a modern commuter car for North American rail lines. Later the Comet moniker was adopted by New Jersey Transit for all of its non-powered single level commuter coaches. Additional series of cars bearing the Comet name based on the original design have since been built by Bombardier Transportation and Alstom. The successful design was adopted by numerous commuter agencies.
