train delayed - taxi involved!

(a new one on me, by way of reasons for train delays...)

My 12:15 train from Leicester was delay 100 minutes due to a 'police incident' at Birmingham (which turned out to be as below).

A spare train was parked up after about 30 mins while announcements explained the train crew were on their way from Birmingham by taxi.
