Height of Maud St Bridge near Waratah for rail traffic?

 
  Newcastle Express Chief Commissioner

Would anyone know the height of the Maud St Bridge for rail traffic near Waratah? And the sources I have don't help.

And also curious, could a double deck (without a pantograph) fit under the bridge? (Of course, I'd don't think they would be able to fit when passing stations!)

A K set side by side with an Endeavour rail car look about the same height if the pantographs are disregarded. I don't have the technical data to confirm whether this is more than an optical illusion.

A Hunter rail car fits under the Maude Street bridge with apparently not much to spare. Again I don't have technical data, but I have photos tending to support these suggestions.

I can tell you that the grade up to the summit over the Hanbury Dive is 1 in 76 (source NSW Curve and Gradient diagrams), and the distance from the bridge to the dive is approximately 80m (source Google Maps and some use of the distance scale). So lowering the main line rails under the bridge by one metre would just about double the gradient over the 80m to the summit.

There would also be the question of clearance under station footbridges and what that would do to the platform levels if you lowered the rails, although the platform length and width to rail centreline might also be issues suggesting full reconstruction of the platforms. I presume that you are thinking in terms of operation of electric rolling stock to Maitland. (Let's not even mention Warabrook.Smile)

Don't know the height but yes to the second.

4.4m is the safe clearance of all designs with panto stored. V and Ks are 4.368m

A 81 class is 4.26m and they have plenty of clearance under that bridge.


(BTW: Endeavour is 4.11m)

Thanks Jim K, that's interesting, especially the 81 class.

A diesel powered DMU double deck for the Hunter Lines anyone? (Just joking)

(Could always do what the government did in the mid-1980's or so and use loco haul some double deck trailers (Just use V-Set trailers instead!). I think any other double deck would not fit past most of the stations west of Waratah! (Just kidding again!, and besides I think the V-set trailers might have too much of an overhang at places.))

The new link road bridge at Sandgate looks even lower than Maud street.
