Unless it was just a flat upper area with a canopy

Fascinating. Ooh, there's a plaque! I'm inclined to agree Vrs.

A desultory sketch. Not that Im going to attempt this but couldn't resist a guess while in a caff. Be worth a build Vrs, especially interiors. Im refining the 1836ish scenario thanks to your expert research skills

This image is very good Vrs

Is it the case therefore, that the entrance way (and indeed entire surviving structure) is not the original arrivals station, but a build for the new viaduct?

Exactly. Its often exciting like first routefinding a well visited mountain. And hopefully we can offer new views.

Genius

Looking more carefully, there was a passageway from that left doorway with doors and windows presumably to the stores/stables and on the other side...

Brilliant Vrs.

I have now Vrs, thanks so much. Though struggling to get decent clarity. Some views of the earlier scenario, including an interesting one by Shaw showing the same cluster of buildings but still an issue re identification

And presumably this residual facade was the entrance? Though then two storeys??

Wow, thanks for all of this as always Vrs. Looks like a lobg way to go and the sources seem scant.

Well they were pushing the envelope

That's kind of you to say so Vrs.

Hi Vrs! That would be nice. A self-motivated journey of discovery as always.

It is isn't it Ursula? And a beautiful bit of engineering. Hope alls well
