Good afternoon all,

A bit of news about Somerleyton Bridge.
Can you please relay on to all those who might be interested.

Thanks

John

Officers of the Broads Authority and Network Rail have been meeting regularly over a long period to discuss the significant problems that arise for boat owners when the two swing bridges at Reedham and Somerleyton are unable to open in very hot weather as a result of the thermal expansion of the rails.

One of the potential short term measures considered was to cool the rails by spraying water on them. There is no fresh water at Somerleyton and the engineers have concerns about the impact of using semi-saline water on the bridge structure.

However, given the current very high temperatures, the company is going to pump water out of the river onto the Somerleyton bridge for the next two weekends as a trial in an effort to keep it operational. Boat owners should therefore be aware that water drawn from the river will be cascading off the bridge back into the river.

Network Rail is doing its best to obtain the necessary equipment so that water spraying can commence this weekend.

I would be interested to hear from Network Rail if this has been a problem for the past 100years. If not is it due to the replacement of short lengths of track with continuous welded track? If so it is down to Network Rail to sort it. I can recall isolated instances in the past but not as often as this. Or perhaps it is all because global warming!!!

It would also reduce the expansion if the track on the bridges was painted white to reduce the heat absorbsion.

Why don't they try painting the rail white plenty of white paint available. I had a steel boat some years ago it had grey anti slip paint on the roof, when the sun was shining you could not beer your hand on it,i thought about frying an egg, i painted it white i could not believe the difference on a day like today you could put your hand on comfortable amazing what a colour does.
