Gibbs (New York City Subway Car) - Background Information

Background Information

As New York's IRT subway was the first attempt at an underground heavy rail subway, the IRT and chief engineer George Gibbs felt compelled to develop a subway car that would be stronger and safer than any previously designed railway cars. This inevitably led them to the conclusion that it would be best to design an all-steel car to run in the new tunnels.

However, car manufacturers of the time were unwilling to undertake such an experimental proposition. Steel was deemed too heavy for any practical applications. Conventional wisdom of the day (since proven to be false) held that an all steel car would vibrate itself to pieces, for wood was "necessary" for its damping effects on the car's vibration. It was also widely believed that a steel car would be very loud, and poorly insulated from temperature extremes such as heat and cold. With a large backlog of orders for wooden cars, manufacturers had no incentive to explore the new technology as there was still plenty of demand for wooden railcars. The IRT knew that the October 27, 1904 opening of the new subway route was fast approaching, and that rolling stock had to be designed and built soon or the line would not be ready. With time running short to order rolling stock, a protected wooden alternative known as a Composite had been designed and ordered. But that did not stop Gibbs from his pursuit of an all-steel subway car.
