PBKA

PBKA is a high-speed trainset, built by the French manufacturer Alstom for international services operated by Thalys, which later merged with Eurostar. The designation "PBKA" refers to the original planned routes linking Paris, Brussels, Cologne, and Amsterdam.
The PBKA belongs to the TGV family of trainsets and was designed to operate across multiple national railway networks. Each unit is equipped to run under four electrification systems: , , , and .
The PBKA was originally intended to serve as the sole rolling stock for Thalys, but due to the cost and complexity of its quadri-current capability, seven simpler tri-current versions, the PBA, was also ordered. The PBA omits equipment for operation under Germany's 15kV AC system. The two types are interoperable and can operate in multiple when coupled together.
Each PBKA set is long and weighs about. The trains comprise two power cars and eight passenger coaches—three first class, one bar, and four second class—offering 404 seats in total.
Maximum operating speeds and power output vary by voltage: up to with under 25 kV AC, with under 15 kV AC, and with under 1,500 or 3,000 V DC.
A total of 17 PBKA trainsets were built between 1995 and 1998. Of these, nine were funded by the National Railway Company of Belgium, six by SNCF of France, two by Deutsche Bahn of Germany, and two by Nederlandse Spoorwegen of the Netherlands.
