To clarify Ian’s post:
R1 = 2’ radius.
R2 = 2.5’ radius.
R3 = 3.75’ radius.
R5 = 7.5’ radius.
These are the curve designations given to LGB’s brand of track. For reliable operation by 90% of the trains in our scale, I’d go with nothing less than R3. Many will tell you that a working minimum is a 5’ radius. This isn’t absolute, but it’s a good standard. R3 is certainly workable in tight spaces.
Aristocraft, the other leading manufacturer of sectional track, lists their track in terms of either radius or diameter (sometimes interchangably.) They make track in 2’ radius, 5’ radius, and 10’ radius sections. USA Trains also makes sectional track, though they are a distant third in the marketplace.
The track that comes with the starter sets from almost all manufacturers is 2’ radius. If you go that route, you’ll want to buy additional track with a wider radius. LGB, Aristocraft, and USA Trains track will all interconnect without difficulty, so don’t worry about that. Bachmann’s track is crap. Even they admit it. It’s not designed for outdoor use at all, so if you get a Bachmann starter set, just throw the track out and get some real stuff from the other manufacturers.
LGB, Aristocraft, Bachmann, and USA Trains all make workable starter sets, though I’d have to agree that LGB is probably your most bulletproof option there. Depends on where your interests lie, though. Aristocraft and USA Trains make starter sets featuring modern standard gauge equipment. The train in Ian’s signature line is typical of an LGB starter set. As much as I like Bachmann’s stuff, if you’re just starting out, I’d steer clear of their starter sets. Buy one when it’s on sale and you have an existing railroad already.
You may find it cheaper to buy a locomotive, track, and power supply individually, rather than going with a starter set. If you’re a fan of narrow gauge trains, again I’d start with an LGB locomotive and cars. If you’re more of a standa
