Lionel 700K Scale Hudson Kit 1939-42

April 1st, 2008

Lionel 700K Kit Hudson Assembled In Primer Grey

In 1937 Lionel introduced the famous 700E Hudson locomotive. This was a scale 1:48 model of the New York Central steam locomotive. The assembled 700E came with a walnut display stand and was the first commercially produced die cast O scale locomotive made.

The 700E Hudson was very popular with the newly emerging O scale operators. By the mid 1930s a movement towards scale or realist locomotives had grown up in the US and many operators built kits. Factory assembled scale locomotives and cars weren’t available. So the Lionel Hudson was a first.

In 1939 to accommodate O scalers who wanted to build their own locomotive Lionel began offering the 700E in kit form. 5 kits built the locomotive and tender, and a sixth kit contained a whistle for the tender. The kits could be built for inside or outside third rail.

To make it easier for modelers on a budget, Lionel sold the kits separately. Some modelers built the locomotiove and never painted it black so there are a few original gray 700K locos out there. (The one shown at the top of this page is an original kit locomotive assembled and unpainted.) I always wanted to build a 700K so since I had acquired most of the parts I decided to build my own Hudson kit.

The first kit 700K-1 came with the frame with wheels mounted, the crossheads and valve gear.

The second kit 700K-2 included the motor, e unit, collectors - inside and outside, the headlight and a lead weight.

The third kit contained the boiler and cab assembly and all the trim. Below is a photo of a Hudson boiler without the trim installed.

Here’s both sides of the boiler after mounting trim. I set the boiler on the frame with wheels for these pictures.

As I get further along in the assembly of my Hudson I’ll add more pictures and update this page.

700K-4 contained the ash pan, ladders, coupler and pilot, boiler front and some small bits of valve gear that attach to the boiler.
