The 19045 / 19046 Tapti Ganga Express is an Express train running between Surat of Gujarat and Chhapra Junction of Bihar. The train is named for the Tapti River in Surat and the Ganga River in Chhapra. It was introduced in 1990 by George Fernandes to run between Surat and Varanasi Junction, but in Railway Budget 2012–13 it was extended up to Chhapra Junction.
