Wiener Linien spokesman Daniel Amann said: 'Our controllers are well trained to recognize what disturbs other passengers.

The company claims it has been experiencing increasingly odd activities on board its transport network.

There has been an increase in the number of naked passengers, and on one occasion a couple were found having sex on board.

In another bizarre episode, a passenger brought their pet horse onboard.

Mr Amann added: 'This of course goes way beyond the 50 Euro fine. These matters are for the police.'

In 2009 kissing was banned on the platform at Warrington Bank Quay railway station because couples who were romantically saying farewell were making the trains late.

To tackle the issue, a special 'kissing zone' was set up in the short stay car park.

Here, couples using the station were given 20 minutes to indulge their amorous feelings toward each other.
