Dundertåget was a Swedish rock band formed in Stockholm in 2004 by Robert "Strängen" Dahlqvist, guitarist of The Hellacopters. Starting out as Thunder Express, they switched to Swedish-language lyrics in 2008 and renamed themselves, going on to release four albums on Razzia Records before disbanding in 2011. Their 2009 debut under the new name, Skaffa ny Frisyr, earned a Grammis nomination for Best Rock Act of the Year. Dahlqvist passed away in 2017, and in June 2026 the remaining members reunited for a tribute performance at Sweden Rock Festival.
Dundertåget (billed as "Dundertåget med vänner") performed at Sweden Rock Festival on June 3, 2026 - their first concert since frontman Robert "Strängen" Dahlqvist's death in 2017.
Guitarist Robert Pehrsson confirmed in an April 2026 interview that no further shows had been decided, but that interest had exceeded expectations.
The Sweden Rock Festival announced Dundertåget med vänner as a booking for its June 2026 edition, with guests including Stefan Sundström, Nicke Andersson and Pelle "Hellbutcher" Gustavsson.
