While this may be a common feature on modern high-speed turnouts, it was one I hadn't seen before.

This pic shows the join

The turnout is pretty long, this is most of the switch half, the diverging lines are only about a foot apart even with this length

Possibly the other half of the turnout, and some Streamline ;-)

Has anyone ever seen this type of turnout modelled?

Hi Tim,

Many thanks for the pics.

It is now common practice to use a special rail section for switch blades. There are some detailed pictures and rail section drawings on this page:

I don't know of anyone modelling these RT60 turnouts. Modelling of UK standard-gauge flat-bottom turnouts in any form is uncommon. Anyone?

regards,

Martin.
