It is important to for your train to turn around on your layout and for that you'll need to integrate curves in you tracks well, much depends on the size of your curves. There are basicaly three general sizes of curves in model railroading, SHARP, CONVENTIONAL and BROAD. they are different dimentions in different scales but this site is about HO so we'll go with that one. Now because the chasie of alocomotive can't bend throug a turn the curve can't be to tight, if it is the front wheels will come out from between the rails, causing a derailmen and some embarasment and agrivation

The size of one's layout will be affectet by the size of the curves desired.
