MTR Express
MTRX is a Swedish company running open access intercity railway services between Gothenburg and Stockholm. It is a subsidiary of MTR Corporation through MTR Nordic.
In July 2013, MTRX was awarded paths to operate services between Gothenburg and Stockholm. MTRX commenced operations on 21 March 2015. It has purchased six Stadler Flirt electric multiple units.
In July 2017, MTRX made headlines after a public poll to name one of its trains led to the name "Trainy McTrainface", in a nod to the near-naming of RRS Sir David Attenborough "Boaty McBoatface" in April 2016.
