Hudson Locomotive Action

The following three animated image files show how each locomotive model's drivers and linkage operates. The first image comes from a model of an un-streamlined Hudson. On the real Hudsons the linkage and side rods were very similar between the J-1e and J-3a. The scale J-1e model shown below has prototypical motion and components. The two Dreyfuss models illustrate the lack of these particular qualities. However, both Dreyfuss models have dulled linkage and side rods, which look more realistic than the shiny chrome linkage and rods of the 700E.

700E Scale Hudson

This is the reproduction of the J-1e Hudson made by Lionel Trains, Inc. in 1990. Notice how all the linkage has motion. The piece that slides from side-to-side above the crosshead is called a radius rod. Also notice in the upper right corner the small lubricator lever. The components shown on this model are identical to the original 700E model which was first produced in 1937.

MTH Dreyfuss Hudson

This is what the MTH model of the Dreyfuss looks like in operation. Compared to the 700E, there is less linkage motion. The radius rod is static. There is no lubricator lever. The combination lever bends out from under the valve guide and down to the crosshead assembly. On the 700E, it is more prototypical as it is a straight piece. The blackened tires of the drivers should be silver.

Lionel Dreyfuss Hudson

With regards to linkage action, Lionel's model has more in common with the MTH model than with its own 700E. The static radius rod, the bent combination lever, and the lack of lubricator lever are identical to the MTH model. The black screws that secure the drivers to the axles look like holes that shouldn't be there.
