A multiple unit train running on liquefied biomethane has received certification in Italy

The Railway Safety Agency ANSFISA has issued the authorization for the operation of a modernized ALn 668 multiple unit train model, originally produced by FIAT in the early 1980s, as reported by the railway magazine Railway Supply, citing Rollingstock.

It is planned to use this train on the Sulmona-Carpinone tourist line.

The project was implemented under a memorandum of understanding signed in 2019 between the national carrier FS, Hitachi Rail, and the gas transportation company Snam.

Major repairs to the bogies, transmission systems, engines, and other components, as well as the refurbishment of the interior, were carried out by FS at the workshop in Rimini. Hitachi Rail was responsible for converting two engines to run on liquefied biomethane.

It is claimed that this will reduce CO2 emissions by 20%. As part of the modernization, the total power of the engines was also increased from 340 to 345 kW.

A total of two multiple unit trains have been modernized, but the certification for the second one has not yet been completed.
