At the LDCR/SECR Greenwich Park station, there were 2 platforms with an engine release road between them also leading to a pit. So 2 crossovers on top of each other, to make a 3-way in the middle.

I read the thread "3-throw turnout for Richard Lambert" but it does not really help. So before I start are there any good tips for drawing and making a 3-way ?

I presume I can follow the tandem video for most of this, but one immediate question is how to get the staggered toes ?

Hi Mike,

Richard Lambert's excellent topic on Old RMweb covers the building of an 0 gauge 3-throw turnout in detail (4 pages):

The 3-throw starts on page 3:

???

Tandem turnouts have staggered switches, as in the video.

3-throw turnouts don't have staggered switches, the switch blades (points) are coincident and overlap.

regards,

Martin.
