As usually happens with FasTrack, there are lots of little sections (1-3/8, 1-3/4, 4-1/2). Lionel ought to package them by the dozen for a discount. OR (better), Lionel should introduce a small expandable section (not kidding), that I have shown before, and is available in
Z gauge Rokuhan. and Kato N Unitrack
And add it to their S FasTrack as well. Lionel could make good bank with this section, and more folks would be inclined to build FasTrack layouts if it is easier to make fractional connections. [And would save me tons of time😉, optimizing is the most time-consuming aspect of designing FasTrack layouts to tight specifications.] I submitted the idea to Lionel by email - fingers crossed!
