I am new to model railroading. I had Lionel O27 as a kid but now that I am retired I want a real train layout and am going HO. I also have a new grandson so I bought Thomas Fun With Freight set. My plan is to use Thomas around the Christmas tree until he gets old enough to play with it. My plan is to let him run his train on grandpa's layout. I have done some test runs on old stuff I acquired from a friend and Thomas jumps track when going over an Atlas brass code83 snap switch turnout. I have seen people say to grind the flanges on Thomas' wheels ro to modify the turnouts, etc.

I say all that to lead to this question.

I am planning on using Atlas code100 track snap track for my layout but am concerned about Thomas jumping off rail at the turnouts. Has anyone used Atlas code100 snap track snap switch turnouts to run Thomas? How successful was it? Any modifications needed to Thomas, the turnouts, etc.?

Thanks in advance for taking time to read and answer.

BTW - I know that Atlas code83 snap track is more prototypical but I am concerned about being able to run some vintage HO equipment and heard that code100 track is easier to use with older cars and engine.
