This is from an old railway magazine I’m reading.

Why should this particular structure be regarded as “a real horror story”?

It certainly looks a bit unusual, but I’m not sure what the “horror story” is about. It might be very corroded (hard to tell from the picture), or it might just be a bit of journalistic exaggeration.

I think the implication from the article is that this kind of design itself is potentially dangerous. The article was written by one of the civil engineers employed by BR to help modernise the infrastructure with better designs.

Could it be simply that it is about ascetics with the bridge looking a lot stronger than it is?

You mean aesthetics. No, the concerns here are practical.

Another example of the structures they were anxious to replace.

If they were adding bits and pieces over the years without proper consideration of the effects on the original structure that would certainly be a cause for concern.

Can y’all find that intersection in Google Street view? Signs says Rostron (presumably the street or avenue) but I can’t find the railway crossing. Sounds like a job for Sm.

Seems to fit the information we have, but:

Where have all the houses gone?

This one is obviously a horror story from the point of being hit by trucks passing underneath. There is not even any reliable “maximum height” value for trucks because the maximum height varies enormously depending on where on the width of the road the truck passes.

The second one also with steel underneath there is a difference in the truck maximum height in line with the steel supports and out of line with the steel supports.

The third one not so much. But removing the girders would increase the maximum height of trucks passing underneath enormously.

In each case the removal of underbridge steel would result in an improvement in the maximum height requirement for trucks passing underneath. Perhaps that’s what they mean. A heavy truck impacting the bridge could cause a lot of damage.
