Where can I find a guide as to the radius needed for different Locs and coaches? Any and all help appreciated

Generally most G1 locos and coaches require a minimum radius of 1020mm to run on, but the larger the better.

Very little is intended to run on 600mm radius curves, mainly older Maxi items.

Hi,

Do you know the overview showing the Märklin - track-assortment: https://www.maerklin.de/...pur_1_Gleisplakat_A1.pdf ?

Such a large radius can be made with the 5998 - track- - construction - kit. Have a look at the manual how it can be assembled to make large radius tracks: https://static.maerklin....acf8141a061434542590.pdf

Regards

Markus

Converting can be tricky. Especially European to US curved tracks – radii in mm versus diameter in inch or feet. Sometimes to center of rail and maybe even outside of ties.

10 feet will give you just over 300 cm if my conversion is correct. Note that you can ease the curves. That is, starting and ending the curve with a large radii and use tighter curves in the center of the curve. There are also manufacturers of flex tracks. There are a number of track suppliers in the US. Then the code is also a matter to consider.

I suggest you play with a track planning program with the tracks of the manufacturers you consider. Checking G-scale forums might be a good idea too.

OneGauge Marklin and MTH, ESU ECoS 2.1 on LGB tracks. MTH 3-rail 0-gauge, DCS on GarGraves tracks. Z: Rokuhan tracks, analog or DCC+TC Gold.

so if I use the 5935 which is 22.5o that should bring me down to 7 ft will that be too tight for a 5797 (4-6-0) which is the largest Loc I have ?

Hi Joel,

The 5797 (class 38) runs on the 5935 tracks with 1020 mm radius (6,7 ft diameter). That does not really look good, but it works. When that loco came out, 1020mm was largest radius available from Märklin.

Hi Joel,

I would agree with Markus but my experience is some locos although built by Marklin to go round 1020mm radius corners do so with a sense of humour failure at speed. The 78 and Krocodile are the worst as Marklin do not have very clever springing for the trucks so they climb up the outside track and look for an opportunity to derail. The 38 is better in my experience. I have not tried any of the more modern and expensive locos to see if they ride better.
