A Bangkok - Ubonratchathani rapid train is creeping along, slowly.

An hour into the journey and it creaks to a halt.

Somchai sees a conductor alight the train and walk outside.

"What happened?" he shouts at the conductor.

"A Cow is on the track!" comes the reply.

A few minutes later, the train starts moving on slowly.

Ten minutes later, it stops again.

Somchai leans out the window and sees the same conductor walk again.

"What happened? Did we catch up with the cow again?"

Keep trying road runner, they are getting better!
