Swiss railway operator SBB will be working to renovate and upgrade its fleet of 19 Astoro train sets in the coming five years. The first train arrived at the Bellinzona maintenance centre on Monday, having covered some 900,000 kilometres. The Astoro trains first entered service in 2004 and are set for another 15 following the upgrades.

The body work of the Alstom-built Astoro trains will be completely repainted and will receive and fresh anti-corrosion treatment. The front cabin will be overhauled, and the windows will all be replaced. The same goes for the lights inside and the toilets. In order to comply with the Disability Equality Act, the doors and entrance areas will be revised as well.

Less visible but equally important, SBB will also carry out work on the bogies, front coupling and pantographs, as well as the hydraulics units, valves and compressors. Some 60 people at the Bellinzona will be involved in the maintenance effort. They will work on a total of 133 train cars, split into 7 trains sets from the first series and 12 Astoro series II train sets. The renovation works, which will run until 2027, carries an investment of 120 million Swiss francs (121,4 million euros).

SBB uses the tilting Astoro trains for international passenger transport to Italy and Germany. The rolling stock can accommodate 430 seated passenger per train and is also approved for use in Austria.
