and electric multiple units, such as the Bombardier Voyager family and the Hitachi A-Train AT300 family, even on express services. Tilting These cars are able to tilt to counter the effects of inertia when turning, making the ride more comfortable for the passengers. Amtrak has adopted Talgo trainsets for its Amtrak Cascades service in the Pacific Northwest. Other manufacturers have also implemented tilting designs. The British Rail Class 390 is a tilting train operating in the UK. Lighting, heating, air-conditioning The earliest form of train lighting was provided by Colza oil lamps. The next stage was gas lighting, using compressed gas stored in cylinders under the coaches. Finally, electric lighting was introduced. Early railway coaches had no heating but passengers could hire foot-warmers. These worked on the same principle a modern sodium acetate heating pads. Later, steam heating was introduced, using a steam supply from the steam locomotive. Steam heating continued into the diesel locomotive era, with steam supplied by a steam generator. Now, electric heating is almost universal and air-conditioning is often provided as well. In the case of diesel multiple units, the coaches may be heated by waste heat from the engines, as in an automobile. In a subway car, tram or train, an insulator at a track switch may cut off power from the car for a few feet along the line and use a large capacitor to store energy to drive the subway car through the gap in the power feed.
