This question could actually be about any railway which is about to be electrified

On my frequent jouirney from Thatcham today I wondered what happens tpo level crossings when a line is to be electrified.

I don't know what clearance between road level and the overhead cabling but how does that height compare with , say, a double decker bus?

In thatcham the option to change to crossing into a bridge would be challenging to say the least so if height is an issue what happens

OHLE is raised to a slightly greater height than normal over level crossings, (albeit within the ambit of a normal pantograph) and that height is well above whatever the 'low bridge' definition is, 16' 6" apparently after some research.   I think there might be some additional warning signs when wires are present, Google Street View should confirm either way.  For example here at Waterbeach, north of Cambridge, there are signs showing 'safe height 16' 6":  http://goo.gl/maps/xUZQ

It isn't a significant issue though, there are level crossings all over the AC electrified railway elsewhere, such as on the GE, the ECML and previously the WCML, although most of the latter have been bypassed as part of the route modernisation.  But the latter was all about increased train speed and train frequency, nothing to do with the risk of high vehicles causing problems.

I like the Network SouthEast liveried HST in that .pdf  :o
