Here's a couple closeups of track comes in sets.
It is essentially folded tinplate.
Now, before anyone starts dissing that kind of track, please submit a report on prices per foot of outdoor track with UV resistant ties and show pricing of sets with that track substituted for factory track. Or alternately, pricing of sets including material and tools to construct handlaid track.
not shown are clips which secure sections to each other

It's not a matter of dissing Bachmann track. It's just a simple fact that it isn't made to be used outside because there will be a race between the rail (rusting in the elements) and ties (disintegrating due to the UV) to see which one perishes first.
There is no question or argument that Bachmann track is much cheaper than any of the alternatives. But is is limited in terms of what track pieces are available, there is only one tight radius curve, and it won't last outside for a single season.

I have seen many great indoor layouts made with this track, many have modified the track to meet special needs. It is just fine for what it was designed for, and easy to tweak.
