Model Forum / General / Railroads / February 2005Bachmann Branch line loco's
Hi, I'm looking at buying a new loco (steam) for my (small) layout. Looking through the Bachmann Branch Line catalog, I quite like the LMS Crab's, the Collett Goods, and the Ivatt Class 4's. But, the catalogue, unlike the Hornby one, does not state if the loco's are suited to 1st radius curves. Can anyone shed any light on whether any of the above can run on 1st radius curves ? (Before some of the purist's go off about 1st radius not being scale, I do this for my personal enjoyment, not to do it to scale/historical accuracy - and I don't have much space available) Thanks in advance, Ian > Hi, > [quoted text clipped - 12 lines] > > Ian Just what is a "1st radius" curve? Can't you just specify in inches (or cm)? Besides, different "systems" have different specs for "1st radius/small radius", etc. >> Hi, >> [quoted text clipped - 16 lines] > cm)? Besides, different "systems" have different specs for "1st > radius/small radius", etc. I don't mean to flame Wolf but IIRC in the UK 1st Radius = 18" for 00 and 9" for N-gauge. This being "uk.rec.models.rail" the original poster's terminology is perfectly valid. (kim) >> Just what is a "1st radius" curve? Can't you just specify in inches (or >> cm)?

First radius is 371 mm. according to the latest Hornby catalogue, which when dividing by 25.4 gives 14.6 inches. >and 9" >for N-gauge.

Most of the larger Bachmann and Hornby locos require *at least* 2nd radius curves, and I'd certainly suggest that the Crab and the Ivatt 4MT (when it's eventually released) will want the larger radius. The Collett 0-6-0 should be ok on first radius. John. >Hi, > [quoted text clipped - 3 lines] >But, the catalogue, unlike the Hornby one, does not state if the loco's >are suited to 1st radius curves. Yes it does. Look at the Contents page (page 3). The first sentence after the table of contents says <quote> Bachmann Products are not recommended for use on First Radius Curve Track. </quote> > Can anyone shed any light on whether any of the above can run on 1st >radius curves ? > >(Before some of the purist's go off about 1st radius not being scale, I >do this for my personal enjoyment, not to do it to scale/historical >accuracy - and I don't have much space available) I don't think anybody has the right to complain about 1st radius not being scale, because even in the most fine-scale of layouts there are many things that are not to scale. Just make sure you enjoy yourself. >Thanks in advance, > >Ian SignatureJohn Sullivan OO in the garden http://www.yddraiggoch.demon.co.uk/railway/railway.html I doubt whether too many purists could have scale radii on their layouts. 5 chain curves, mainly on sidings, traversed at 2 or 3 mph by little shunting locos, have an OO equivalent of 4.34 feet, 10 chain curves, most branch lines, OO equiv. 8.68 feet radius. 20 chains, probably minimum on main lines, more than 17 feet radius. Who has sufficient undercover space to use such scale curves? Most of us because of space limitations, are lucky to be able to use 4 ft. radius curves, less than 5 chains in real life, around which we run our expresses at speeds often well in excess of a scale 60 mph! But it's all compromise. Regards, Bill. > >Hi, > > [quoted text clipped - 25 lines] > > > >Ian |
