Of course like many other model railroad fans I received my first train for Christmas, for me it was in 1956 or possibly 1957. It is the O27 Lionel set 1559W from 1955-56. You can see the owners manual (1st photo) needed a little color and as a 4 or 5 year old I willingly provided the color, obviously I was better model train operator than artist!
In the second photo is the train today. It is the orange and black Milwaukie Road engine, barrel car, with the original cars: barrel operating car, truck car, operating box car, auto-loader car and caboose. All are intact, and the diesel runs great. This photo was taken a few months ago, while it sat on my club's layout (2nd photo), in the O-gauge LSD Room of the MSMRRE. It had about 45 years to rest, in it's original boxes.
For about the first 10 or 12 years my model railroad was a main attraction beneath our Christmas tree. My dad was the main proponent to expand the set to include 2 remote switches and an additional track to expand it to fit on a 4' x 6' platform with an outter loop the next year. Following year we added the red NYC culvert gondola and the Lionel Culvert Unloader. The UP switcher (1958) was provided by one of my neighborhood buddies; I am not sure what I traded for it, but I got the better deal!
I was reminded by another post here that I too use to lie on the floor at the end of the platform, the track was about 4 inch off the floor. I really enjoyed seeing the diesel locomotive speed straight at me, and then turn "just in time!" Girls, cars, and rock n roll determined the start of the 45 year "rest." My foster son, and then my stepsons were all came along at an older age than I when I first got interested; besides they had other interests when I joined their families. So that contributed to this train's long rest in the boxes. My imagination and that train took many "trips," imagining what I would see and do if I was riding that train. If I was small enough to fit on that train.
Since I did not have the right timing with my sons, I have been making up for lost time. I have been very busy this past 12 months getting my 4 grandkids (ages 3 to 6) interested and started with their own RTR Lionel Trains. Now I am getting ready for an even better Christmas with them!
