[citation needed] An example of these are the Acela Express trainsets in use by Amtrak, which are built by Bombardier in Canada using technology licensed from France's Alstom.

Another traditional example would be the older InterCity 125, made for and used by British Rail and several subsequent privatised bodies like Great Western Railway.

Each coach then picks up the power supply through a 60 kVA transformer and brings down the voltage to 110 volts, at which the equipment in compartments run.

This system is leading to huge savings in diesel fuel consumption (amounting to ₹1,182 crore (US$140 million) as on 20 November 2019).
