About this converter
TGV tops run 270 to 574 km/h in this table. Sud-Est at 270 opens the short end from 1981. Atlantique, Reseau, Thalys PBKA and Eurostar e300 each sit at 300. Duplex, POS, Euroduplex, e320 and TGV M each sit at 320 service. Turbine prototype at 318 sits near service tops. V150 test at 574 tops the table as a test run, not service. Every figure is top service speed unless noted test, from SNCF and Alstom specs. Operating limits differ by line, so line caps are noted per row.
How to use it
Pick two trains and a unit in the top row. The three boxes below stay linked. Change any box and the other two update. Try 1 V150 Test against 1 TGV Sud-Est to see the 574 to 270 gap. All rows use km/h, so the unit stays fixed. Click any table row to load it as Entry A with amount 1.
Values pin top service speed with test noted where used. V150 at 574 is a 2007 test on a closed track with larger wheels, not daily service, noted as such. TGV 001 turbine at 318 is a prototype test. Eurostar e300 and Thalys run 300 on classic lines and 320 where allowed, table pins 300 service. Line caps stay out because train capability is the topic.
