Hello.
I run M tracks, but I've the opportunity to buy a complete set of K tracks: +/- 140 mixed tracks parts.... ! no powered ones !.... no sure about railway switches.
Global package around 60 euros (For me, K and M are equivalent, so I think the offer is good.
My idea is to have my outer loops based on K tracks (no signal but switches to enter M inner circuit), while the internal part of my layout (locomotive shed, stations, ...) will be based on M tracks.

Question 1: Do transition parts exist ?
Question 2: Can M powered part power K circuit ?
Question 3: for switching for K circuit to M one, is the following idea "K_switch -> transition part -> M track" a option ?

(Nb: sorry for my english... when I say 'K switch', I think for instance to part 2262 of marklin K stuff)

Thx
Phil

Thx.
So what is the best workflow to transition from K to M through switches ?
Phil

I think this will be difficult to do with only a inner and outer loop, you can not connect a K-switch to a M-switch together, and as said the only transition part available is a straight 180 mm track.....

I started with M track. In the 1980s I got some K track because you could get larger radii which was important for me to show off my 1/87 Roco coaches. I had a parade layout of R4 and R5 curves with an inside track of M track R2 and R1. By skipping R3, I was able to put the adapter track between the two. I used the M track as a local/regional line and the K track was the mainline. This was all set up as a teppichbahn on the floor from time to time. These days, I am almost exclusively using C track. I went back to the K track when my original C tracks starting cracking, but the newer ones (post-2005) are much less prone to deterioration. For digital operation, the combination of tracks can be problematic, as transitions can cause weak spots that can be damaged with constant power supply. I had one K to M track where one of the little metal pins somehow touched the metal of the M track and this caused a little heat damage without the transformer tripping.

Ok, it is clear now : Kswitch__transition2291__(eventually one M straight like 5106)__Mswitch to enter my internal M circuit.
