The Niederflur-Express-Triebzug (NExT, {{langx|en|low-floor express trainset}}) is an electric multiple unit light commuter train developed by Stadler Rail for the Swiss Regionalverkehr Bern-Solothurn (RBS) railway operator. With a top speed of {{Cvt|120|km/h}}, it is the fastest metre gauge train in Switzerland.

Six three-carriage trains were delivered in 2009 at a cost of 53.4 million CHF and are used for express service between Bern and Solothurn.{{cite news|title=Schnelle Züge ohne Zigarre: Berner Pendlerbahn setzt Masstäbe punkto Design und Komfort|date=6 June 2009|work=Neue Zürcher Zeitung|pages=11|language=German}}{{Cite web|url=http://www.rbs.ch/unternehmen/fahrzeuge/next|title=Der Niederflur-Express-Triebzug NExT|website=RBS.ch {{!}} Regionalverkehr Bern-Solothurn|language=German|access-date=2016-10-09|url-status=dead|archiveurl=https://web.archive.org/web/20161025190708/http://rbs.ch/unternehmen/fahrzeuge/next|archivedate=2016-10-25}} In 2013, 8 additional trains were delivered.

The Neue Zürcher Zeitung commented favourably on the train's angular design and use of interior space. It commended RBS for setting "new standards of design and comfort" in Swiss commuter transport with the NExT.
