The track far right is triple gauge, were they 4'8½" (British standard), 5'3" (Irish standard) and 7'¼" (Great Western broad) gauges?A print of Curzon Street , Titled ‘The First Railway Passenger Station in Birmingham (1838) source Historicengland.org.uk
Forget it ! I was looking at an enlarged version which hid the fact of two tracks crossing in the foreground! All are normal 4'8½" gauge tracks.That is the only conclusion that I could come to, but cannot find any evidence that the GWR, ever ran Broad gauage into Curzon St. There were parliamentary bills to this effect, and the Duddeston viaduct was built with this in mind, but never completed. I wonder if this was artist's licence
Can you give us more details please as this sounds as if it might be the viaduct from Bordesley which was never completed.In the Science Museum of images of Curzon Street there is one captioned Curzon Street Viaduct. Not all the plans there were carried forward and this one seems not to have happened and the London & Birmingham Railway build a level crossing instead to reach their goods yard
The original entrance to the London and Birmingham Curzon Street station was to the left of the still standing building which was a hotel in the early days. The entrance to the Grand Junction station was along Curzon Street.As work proceeds HS 2 there is still the lack of recognition in these modern times that there were two stations at Curzon Street; the London & Birmingham Station and the Grand Junction Station. Whilst traffic was exchanged at Curzon Street between the two railway companies they had their own agendas. As new schemes came into existence some would favour the Grand Junction and others the London & Birmingham if they intended to join with their separate routes. One such scheme led to the building of the Bordesley Viaduct as part of the Birmingham & Oxford Junction Railway. That scheme joined with the Grand Junction Railway at Curzon Street. When the Grand Junction and London & Birmingham railway merged into the London & North Western Railway priorities changed and although built the Bordesley Viaduct never saw a train from the Curzon Street end and simply had tracks associated with the goods station which was Great Western Railway
