description TGV POS Overview
The TGV POS is a French high-speed electric trainset developed by Alstom for SNCF. The name refers to the original Paris, eastern France, and southern Germany service corridor, and the trainsets were also used on international routes involving Switzerland. Like other TGV equipment, the POS uses articulated passenger cars arranged around powered end units and was built for scheduled high-speed rail service. In 2007, a modified TGV POS trainset took part in the V150 test that reached 574.8 km/h; that figure was a test record, not a normal operating speed.

Why could TGV POS trains operate in Germany and Switzerland?
The TGV POS was built by Alstom for SNCF with multi-system electrical equipment and signaling compatibility for cross-border routes. That allowed service from France toward Germany and Switzerland rather than restricting the train to French high-speed lines.
Was a TGV POS involved in the 2007 speed record?
Yes, a specially modified V150 trainset used two TGV POS power cars and reached 574.8 km/h on April 3, 2007. That was a test record, not the normal commercial operating speed of a TGV POS.

Is the TGV POS a double-decker train like a TGV Duplex?
The standard TGV POS formation used single-level TGV Réseau coaches between newer POS power cars, unlike the double-deck TGV Duplex design. Its international role and multi-system equipment were more important than adding a second passenger deck.
