BEIJING, July 23 (Xinhua) -- China's railway police authorities have stepped up efforts to crack down on the misconducts of train fare evasion, especially riding outside of the purchased distance, in a bid to maintain good transport order.

The patrol force in train stations has been strengthened by local railway police to scrutinize suspicious passengers who ride without tickets or possess several short-distance tickets, with closer monitoring of irregular ticket purchases, said the railway police department of the Ministry of Public Security Tuesday.

Railway police have also teamed up with local stations and transport departments to enhance the identity check of passengers and remain informed of any suspicious behaviors for further investigation, the department said.
