Fast Track

According to Lionel, the minimum curve for this engine is O-72.

Thank You So Much 👍

0-72 is minimum. It will of course look better with larger curves.

if you can fit larger curves go for it.minimum will get you by,but bigger is less stress and looks better.i have experienced this with atlas maxi stacks.they say 054 minimum but does not look good and i can see strain on couplers.i would always go for the biggest curve space allows.my little table is 7x8 just to allow me 072 curves.you can always put smaller stuff on  a loop inside big loop

Well

my table is going to be 8X8. So I can use O-84 if I go with O-96 I’m going to have to build table 8X10   I think bigger is better. Thanks 😂

Did you get the original box and instruction manual with the loco?  Minimum curve is usually printed on the end flap box label, also likely in the owner's book.   Also, if you look up the loco by item number on www.lionel.com, the radai will be mentioned in the advertising copy.

Yes I have original box. Opened it just to check it out and put it back in box. Should have left the manual out.

If you are using Lionel Fastrack an O96 circle will not fit on an 8ft wide table. Fastrack is measured center-rail to center-rail. The outside edge of the "ballast" is 1 ⅝ in from the center rail. Thus an O72 circle measures 75.25 in from outside edge of ballast to outside edge of ballast. O96 will be 99.25 in. from outside of circle to outside of circle.

Thanks. I decided to go with a 8’X10’ table. It states that O-96 needs 8 1/2’ to complete a turn.
