Joined: 16/05/2020(UTC) Posts: 11		Could I run a Marklin F7 ABA on R-1, M type track, without the locomotives colliding and derailing? I was considering an F7 purchase, but not sure about its operation on the tighter 360mm (14.1") curved sections. Thanks, Doug

I was considering an F7 purchase, but not sure about its operation on the tighter 360mm (14.1") curved sections. Most Märklin locos I know (I have more than 100 of them) run on R1 radius including large steamers like the GG1 and the SNCF 241 A 45 and also the DL800, G800,.. Of course it is up to you to watch things related to overhang of long vehicles: - overhead masts and signals, better located outside of the R1 radius - in some cases, switch lanterns may interfere with very very few cars. - never have a R1 "S" curve (curve followed immediately by a counter curve w/o a straight section in-between - F7 units were designed in 1964 or so when the industrial radius existed and MOST locos and cars of the time could run on it (61 cm in diameter) so they could use smaller radius - avoid using M track switches with large lanterns (until 1970 or so) Cheers Jean
