Cantilevered canopy puzzle

[meonia]

I am in the process of making the old GWR Devonport Albert RD. station for the Glorious Devon Plymouth-Okehampton-Exeter route. A picture of the station can be found here:

What puzzles me is that there appears to be a large, heavy peaked roof canopy on both the up and down platforms that have absolutely no visual supports. How do they do it?

Any info will be appreciated since I would like this station to look somewhat like the original.


Cheers. Mike.

Looks like the platform canopy on the left has large upright support girders at the rear and then there is a building that protrudes out half way along the platform that also supports it .
