Iโve been collecting the Hallmark train ornaments since they started the series. Iโm pretty sure I have all of the, including the โgoldโ limited editions, and excluding the miniโs (Iโve got to look for a complete list one of these days). Almost all of them are too small, but also too heavy to hang on a live tree - I think youโd need one of those old artificial trees from the 60โs with the twisted metal branches to hold the engines!!! I have 79 train ornaments (77 from the series plus the gold Hudson from the 100 anniversary and a Thomas). I display them every year on the TV console.
