The unprecedented floods in the Krishna river basin in Andhra Pradesh have led to cancellation of several buses and trains in the state, leaving thousands of passengers stranded at different places.

Over 300 buses, including state-owned RTC buses, were cancelled on the Hyderabad—Kurnool and Hyderabad-Mantralayam routes, official sources said.

Hundreds of people from Bangalore who had come down for weekend holidays to Andhra were forced to stay back in view of cancellation of buses and train services.

The South Central Railway has also cancelled 18 trains and diverted 29 others due to submerging of tracks at some places.
