H&R Trains touts itself as “Florida’s Largest Train Store,” and we’ll take them at their word. With over 10,000 square feet of space across multiple buildings dedicated to model trains, you can be certain that whatever engine part or specialty caboose you’re looking for can be found within their walls. In addition to the store, H&R has an outdoor railroad garden that will blow your kid’s (and perhaps your) mind. Owners Alice and Don Morris celebrate 39 years in business this December, and they’ll even let you bring in your 2-year-old and let him run wild among the shelves. Just don’t break any of the collectibles! 6901 U.S. 19 N., Pinellas Park, 727-526-4682, hrtrains.com.
