LGB R5 Points

That track diagram is always useful, Phil, but to get the actual dimensions you need to download the PDF of the catalogue page that is referred to under the diagram; the quick answer to the question asked is that an R5 circle is 4640mm DIAMETER, centreline-to-centreline of track, or 2320mm radius if you prefer.

Funny, that diagram shows you some possible configurations, but does not even identify the R number of the switches, for example how could one determine the curvature of the 3 way switch? The diagram shows some "R2" track connected to it, but I know the curvature of the switch is about R1.

Yeah, you need the specs on the individual switches.

There's a table at the beginning of this page that might make an easier summary:

Gentlemen
Thanks for your help. I think an R5 point would fit what I am trying to create but there is only one way to be sure.
Anyone know of a used Left Hand R5 point for sale?
 
Besides the radius.....
A few pointers (excuse the pun) about LGB R5's
One major thing about the R5 switch (and also, to a certain degree, others from LGB and other manufacturers (especially Aristocraft No6 switch)).
Grease or silicon the connecting contact plates/strips and any microswitches (Aristo No6) very well as they can tend to corrode over time and lead to problematical conductivity.
Also take off the normal joiner/fishplates and use clamps as if something does go wrong the switch/point is easy to extract without upsetting the rest of the track.

Could you please tell me what precisely is the function of the "make up" curved track that is normally in the box with the point?

My guess it makes the arc angle from 15 deg to 22.5.

That is the angle of R3 points should you want a parallel track with a R3/R5 point combination....
 
I thought the make-up track makes the combined length of the diverting path of the switch and the track be equal to one "normal" section of R5 track.

The idea is you can take a curve, pull out one section, and insert a switch that replaces the curved section. Makes track plans much simpler.

Doesn't the short curve bring the diverging track to a parallel alignment with the track it has just switched from?

Going by the LGB catalog, a part number 10150 track is included with the R5 switch, a 150mm STRAIGHT track.

Page 142....

So, from this research, it seems whatever curved track was supplied with this switch, it's not as comes from the factory.

Ah, I'm thinking of Piko R5 which is equivalent to LGB R3!
 
Short straight is to make the straight section same length as the relevant set-track straight..

Yes, from memory the short straight makes the length up to a standard double-straight 600mm
