Chessie - that would be a very smooooooth running C-Liner made by LifeLike. One of their Proto-N models and boy does that one run smooth, which is good since I have it pulling passener cars on observation and excursion trips. I only wish I bought the matching powered B unit too. LifeLike nscale diesels have really improved IMHO from only a few years ago. That GP20 Santa Fe is a Proto-N as are the two GP-60's (EMD and SP) and they all run extremely well with a great amount of detail. The LifeLike's seem to run great right out of the box, whereas some of my Atlas diesels need a few hours of track time before they run smoother. I think the Kato's have the best motors, but honestly, LifeLike is giving them a run for their money. Again, just my humble opinion, but Kato better start improving the detailing on their diesels because what Atlas and LifeLike offer at less money is better detailed than any Kato's (BNSF/NS SD70's and CP AC4400's). The Athearns (BNSF and CN SD70/75 units) look great but their motors require much more power to move them along than any of the others. The InterMountain diesels (FT A-unit and SD40T-2) have the most detailing right out of the box - right down to real grab irons and wipers. But hey - this is just my opinion.
Thanks for taking the time to view them and the kind words. It was fun getting them out and taking one quick picture while the sun was just right. And I know most of these engines need weathered even if it's just a little bit...just haven't gotten the time. (Maybe instead of taking pictures - I should be weathering my diesels!) This wasn't the whole engine roster...maybe some other day I'll take pic of the rest and add it to these.
