The second sign is totally unacceptable.
Not sure if this has been said, but the official sign is a phone within the Network Rail control so that trains can be stopped as soon as possible until the bridge has been examined.
Dialling 999 is not a good option in this instance, the number of times Network Rail receive calls this way and the information that is fed through to NR is vague or incorrect.
These Network Rail bridge signs protect the railway travelling public and also allow them to get the Network Rail response teams to the correct location as quickly as possibly, and hopefully if the bridge is not damaged too much it helps to get the services up and running at line speed quicker, with out the silly type of sign that is in this picture.

Something I've always wondered is, what actually counts as a strike for the purposes of notifying Network Rail? What if it's more of a bridge bump by someone driving slowly (e.g. trying to park?) who momentarily lapses concentration and ends up reversing in to it at 5mph? Does speed not really matter with Network Rail wanting to know about any occasions that a vehicle comes in to contact with a bridge, no matter how trivial-seeming?
Speed doesn't matter. Any form of contact with the bridge by a motorised vehicle should be reported to Network Rail with full details given whether it is a gentle bump or an almighty thump.
Network Rail will then get their teams out to assess the situation. By the way I am one of the responders to bridge strikes for Network Rail and have attended scenes where the vehicle has been a right off and no damage to the bridge but on other occasions I have not been happy with the damage and escalated the situation and others have not been happy either, we had one the other month that resulted in the line being shut for 72 hours while major repairs where carried out on the bridge, so yes it is important to report any bridge strike.

What makes you think that you know better than those who, with the benefit of experience, have decided that these bridge strike plates are justified and that the response shown on them is the best one?
The one and only (thankfully) bridge strike that I have been directly involved with was only reported to the emergency services initially, who then passed it onto our Control, who in turn passed it onto me. At some point during the process, the engineers' line reference was missed out, and the whole thing became very confusing (there are two bridges, on different lines, with the same number under the control of the box in question). I'd estimate that it cost an extra two or three minutes, which would have made the difference between getting the approaching train stopped or having it run onto the potentially damaged bridge, had it not been running a few minutes late. Our Control know, without really thinking about it, the informationt that they need to obtain from the caller, and can quickly act upon it. The emergency services, through no fault of their own, are less well placed to deal with that information, and in particular prompting the caller for information that hasn't been provided. In London, how would they know whether to pass the information onto Network Rail or London Underground?
Tom, I totally agree with what you have said here. The number of times information has been fed through to Network Rail from emergency control rooms with information either missing or totally wrong....in the past we have had road names given to us that are over 1/2 mile from the railway!!
In bridge strikes ring Network Rail first, 99% of bridge strikes are not live threatening incidents to the vehicle occupants. Network Rail can stop the trains quickly with new technology that is coming on line. If it was clear that peoples lives are threatened (ie vehicle fire with trapped persons) by all means dial 999 first, but then ring Network Rail, all I am saying is assess the situation and go from there.
Worse case scenario..... vehicle hits a bridge, occaupants wandering around vehicle clearly unhurt but may be a little shook up, you call 999, time lag of 3-4 minutes before Network Rails phone rings, in the meantime a 100+ tonne train goes across the bridge and it collapses. Now you have multiple casualties/fatalities.
Right, I need to get off my soap box now.

E = M * V * V so 5mph should be safe depending on the construction of the bridge, the angle of impact and the type of vehicle.
Also depends on the past history of bridge strikes at that location, could be whatever damage had previously occurred at that bridge the damage that has been caused by this 5mph bump could send it to the next level and the bridge may required repairs.
