A COMPLETE CIRCLE, 4'
You are looking at a GREAT LGB track lot. It is always good to pick it up used when you can, so you can save some money. PLUS this lot is 12 sections, so you can really save on paying shipping just once.
THIS IS A LOT OF 12 sections of the basic curved... LGB's #1100 curved track. This is 2' in radius, with twelve making a 4'-diameter circle, so you are good to go!
The R1 curve makes a 1290 mm (50.8 in) diameter circle. It is the standard curved that comes in the starter sets and is the smallest radius track in G. 30 degree sections means 12 sections will make a 360 degree circle. Good indoors or outdoors.
CONDITION: As you can see, the track is generally quite though used. Rails show a little bit of use but not too much. Some ties may show a little bit of wear, but it generally looks nice.
