It has been a little while since I have seen one of these 25th Anniversary "sticker units". Union Pacific, Norfolk Southern, and CSX have all created heritage unit. Depending on the railroad, these units are either exact replicas for previous railroads, or artistic variations of previous railroads. BNSF has, to date, not created any heritage units. In 2020 (the 25th anniversary of BNSF), they did release ten of these units that sport the heralds of many of the railroads that ultimately went in to making up BNSF.
