This train is delayed due to...

[causton]

Two trains the other day were delayed on the WCML in the evening peak, one because people watching the Flying Scotsman going through would not move back from the train already in the platform to let people who were actually getting on the service train on and off the train, and another train was delayed at the request of passengers (and the traincrew presumably agreed) as "if we wait here a couple of minutes we'll see the Flying Scotsman before we leave"

Interesting article from BBC today on very same thing.

A herd of cows on a railway line has caused delays and disruption to trains.
Up to 60 cattle were spotted walking along the track and going into a tunnel between Hever and Ashurst in Kent.
Network Rail said it closed all lines while animals were escorted on to the platform at Hever railway station. The cows have now been removed and are safely back in the fields.
Trains between Oxted and Uckfield were cancelled or delayed by up to 30 minutes.
Francesca Ryan tweeted the picture of the herd with the caption: "Holy cow!"
She said: "I was pretty shocked as it's not the normal view when waiting for your train."

The picture that goes with it is a caption editors dream.
