Traction layouts

Hi i’m new to this and I would like to build a traction layout. I was wondering how do they get those sharp turns, so that a HO traction layout will fit in a space of about 3’X3’? Do they use flex-track?

Thanks[8D]

Hi NW.
To get the sharp curves, most modellers will use flex track. Some will use hand-laid track.
there are also some pre-made pieces of trolley track that come from Sweden.
You can also get rail made in a proper trolley style with the groove in it.

Do you know where I can get some of this pre-made trolley track or rail made in a proper trolley style?
