Mine at the moment is the Lionel 646 Hudson Steamer shown in the video below:
Why is it my favorite Postwar (PW) engine now? It was made to run perfectly on my 031 curves and through my 022 switches. I bought this 646 Hudson and tender at a train show 2 years ago for about $150, which I think is a great price. I like its size, a little bigger than the 2065 Hudson (that I also love from my childhood) which makes the 646 look more powerful than the 2065, and the detail of the 646 with its metal silver colored handrail is a little better than the 2065.
I also love the beautiful mechanical simplicity of the 646; it is easy to maintain and repair with plenty of available parts.
And when I'm in the mood, which is often, I love the sight and smell of the smoke made from smoke pellets, and the smell of the ozone after the train has run for a couple of minutes.
I have other PW locomotives that I treasure, and my favorite PW engine can change from day to day, but my favorite at the moment is the 646.
If you have a favorite PW engine, please tell us what it is and why.
