I remember the first time I saw the Virginians, and how neat they looked. Whenever I was fortunate enough to be around the tracks taking pictures, and a pair of EF-4s would show up, I almost always got the 310 as the trailing unit. It started to happen almost on such a regular basis, with the 308 leading and 310 trailing that it had become a "tradition." When OMI released their factory painted HO models of the EF-4s, I bought the 308 and 310. On my layout, the "tradition" continues. . .the 310 trails!
