The track plan we have is for M-tracks, but we only have C-tracks and plan on building it in C. I'm wondering if there is an easy way to translate, or if there is any chart we could use? Here are some pictures: https://www.marklin-user...album?u=13037&a=1905 Thanks Mauel

Here are some pictures: https://www.marklin-user...album?u=13037&a=1905 Thanks Mauel The 5100 is the same radius and length as 24130 in C-track. But the turnouts in your track plan are also R1 radius - and there are no R1 turnouts in C. If you use R2 radius (437 mm) instead of R1 (360 mm) it will be possible to build the layout with C-track, but it will be a somewhat bigger. You could also just use R2 for the turnouts and the piece opposite of it to make an even Circle. The R2 tornouts in C are just 24 degrees, so you need an extra piece of 6 degrees to get the equivalent of a 24230 track piece. Best way to test what is possible or not is to download planning software and try different solutions.

Best way to test what is possible or not is to download planning software and try different solutions. Another problem is that the straights are different lengths. Where the M track 5106 is 180mm long, C track has 172mm and 188mm lengths. There is good reason for this when you look at he point geometry, but it fouls you up when attempting to convert from M to C track. The corresponding fractional straights are also longer than the M track counterparts, as they are based on the 188mm straight, not a 180mm straight.

Here are some pictures: https://www.marklin-user...album?u=13037&a=1905 Thanks Mauel Very nice picture from your track plan # 18. Here you get the complete track plan book, even in English for your memories. http://s341536299.online...-layouts-gauge-h0-en.pdf But why not a new try? Get a kick from this https://www.maerklin.de/...C3%A4nzungspackungen.pdf On the other hand, it is a nice challenge to reproduce M-track plans with C-tracks. Knowing the geometry and lengths of the available C-track pieces it is not to difficult. And just an easier overview of C-track pieces outside the big annual catalogue, even it is in German written and the numbers are in cm, mm. http://www.ccbrailroad.c...nuales/marklin_via_c.pdf Happy railroading TEEWolf P.S. @kiwiAlan is correct what he wrote. But Märklin offers also 360 mm C-track. So you can go for a 360 mm straight. This is either 2 times 180 mm M-track or 172 and 188 mm C-track. https://www.maerklin.de/...rrpdb_pi1%5BnoPaging%5D=

Here are some pictures: https://www.marklin-user...album?u=13037&a=1905 Thanks Mauel As it happens, I gave this plan a go quite a while ago when I was experimenting with my track planning software. I never set-up the actual layout, so there might be a few things that need adjusting. This is how far I got. (no frills, draft state)
