Saw the beginning of this where the football team's coach got hit by a grey railfreight sector liveried Class 31 on the level crossing at Wansford station on the Nene Valley Railway (disguised as some fictional place).
The really unrealistic things were that the train apparenlty only suffered superficial damage despite spinning and flipping a coach, the level crossing signs still flashed despite being knocked over and ending up about 10 metres away, it was ages before the ambulances arrived, despite the incident happening right next to a manned signal box and a railway station (it was dark before anyone arrived!) and so on...
