I have a 4x8 O27 layout with an inner 27" diameter loop and an outer loop. Two of my three locomotives have difficulty on the tight radius and have searched all over for a solution in the form of a larger diameter curve without ripping up all of my hard work and dumping money into new track and switches. I tried placing a straight section after every curved section to try to increase the radius but the sway causes the train to act "weegle-woggle" as my 3-year-old daughter says...
