. And how the surface of the concrete is finished to form the

groove?

. . .

Two questions:

1. How is the flangeway formed?

2. Is all new Aussie tram track laid with "T-rail"? (Girder rail

and

some girder rail special work is still available in the US.)

This is T(I?)-rail, the recent Brunswick St Interchange had grooved
rail fitted, curves are also commonly fitted with grooved rail.

3. Is the space between the rails concreted to rail top level or

is

does a thin layer of asphalt bring the pavement to rail top?

For most other renewals, the concrete is poured right to road level
and the flangeway is formed there but with this extension (different
contractor) it is ashphalt on the top several centimetres.
