In the face of fierce competition from Japan, arch-rivals Siemens and GEC-Alsthom cooperated with the Eurotrain joint venture to try to win the new Taiwanese high speed rail system. The unlikely result was this hybrid demonstration train, composed of German ICE2 power units 402 042 and 402 046 and the trailers of French TGV Duplex trainset 224. This May 1998 photo shows one of the German power units, redecorated to match the TGV trailers. The train was tested up to 316 km/h on the German high speed line between Hannover and Göttingen and demonstrated for Taiwanese dignitaries. Modifications for the test included feeding 15kV power through the Duplex roof cable to the leading ICE unit, installing an additional converter in trailer 294224 for compatibility with the ICE's 1000V AC head end power and installing extra data lines between the two ICE units. Electropneumatic braking systems were incompatible, so braking was done pneumatically only. The Eurotrain consortium lost to the Japanese consortium. Photo: Dierk Lawrenz / Eisenbahn-Kurier.

In 1983/84, the TGV 001 prototype was used once again to help investigate problems with the TGV's secondary suspension and develop the new SR 10 secondary suspension. Note that a PSE trailer is inserted in the TGV 001 trainset! Photo: Yves Broncard. Scan: Yann Nottara (ynottara@mail.dotcom.fr) |

TGV Réseau trainset 534 in acoustic impact testing for the TGV NG program, on line LN3, 17 January 1996. To reduce aerodynamic noise, the bogies and parts of the roof were shrouded, windows were made flush by adding a layer of glazing, and gaps between cars were covered with rubber stretch membranes. CX pantographs were also fitted. Photo: Guy Laforgerie (AFAC). Scan: Yann Nottara (ynottara@mail.dotcom.fr) |

A segment of a prototype composite carbody for bilevel TGV trailers. The cross-section is similar to that of the TGV Duplex, but construction is honeycomb graphite composite instead of aluminum. Displayed at the SNCF Bercy open house, September 1996 Photo by Yann Nottara (ynottara@mail.dotcom.fr) |
