Again! High tides too which means even more boats won't be able to squeeze under.

A strange question.

Has either bridges stuck in the open position?

Hi Paul,

I think at some time they must have or why the need for the summer/winter rails being left on the bridges, sadly they are not used these  days. Of course the need for the summer and winter rails could have just been preventative maintenance, in all wakes of life preventative maintenance now seems to be a thing of the past.

I think you will find out it will never fail in the open state, as this would be a wrong side failure, Heads would sure as hell be put out to sacrificed if this did happen. The mechanical interlocking as well as the electrical interlocking would both need to fail for the bridge to fail in the open position. All railway signaling is done to be failsafe.

As for winter/summer rails, these would be standardish 22' foot rails with the exception of about 2" difference to that 22' to allow for contraction/expansion. These would be used by the platelayers/patrolmen to get the bridge working if stuck due to expansion or contraction, to get the bridge the bridge open. Also bear in mind, the channel rodding/ sognal wires also expand/contract, so it their compensator reach limits again this would stop bridge opening until CS&TE linesman arrived to re set the channel rodding/wire, that is all mechanical. The electrical interlocking is far to complicated to even trying to explain in a single post.
