What are the maximum speeds at which IR passenger stock runs?

The typical maximum speed specification for passenger coaches in good condition is 100km/h. Older coaches and those in poor condition can be seen with annotations restricting their maximum speed to something lower, such as 80km/h. Rajdhani and Shatabdi trains and other fast trains of course have stock that can be hauled at higher speeds. The newer LHB design coaches (see below) can also be hauled at high speeds, 160km/h for the air-conditioned cars and 120km/h for the non-air-conditioned ones. Recently [4/05] ordinary ICF integral coaches have been spotted occasionally bearing annotations for a maximum speed of 120km/h (e.g., on the Jammu Tawi - Howrah Exp.)
