Yes, we've all been there. There was an engine, or even piece of rolling stock, that we took a glimpse at and inside said "NO!" In fact there's probably an item we say no to for every one we say yes to.
However, does that piece we put down on actually deserve more love?
Is it like the runt of a liter of pigs like in Charlotte's Web? Or just a caterpillar waiting to become a beautiful butterfly?
I see quite a few pieces that seem to sit on its lonesome while others seem to vaporize either off a dealer's shelves or an online listing.
The 44 Ton Switcher by Lionel is a good example. Many people consider it an ugly duckling for being over-sized and baron of nice details. My eyes see a nice, affordable engine that runs well, has good play value and comes in a few nice paint schemes.
Another example is the 2-4-0 steamers Lionel offered in 1993, essentially upgrades of the despised original Postwar Scout engines. Despite their unimpressive appearance and heft, these improved versions are under $50 today, quiet, colorful and cute.
I'm sure numerous others in this hobby has plenty of underrated favorites out there that they aren't afraid of sharing their stories.
