Welcome to this new model of the EMD SD40-2 for Union Pacific.

A great machine powered by two 12-volt motors per axle, a removable diesel engine and a refrigerated wagon from the Union Pacific Fruit Company.

The reason to build from scratch is due to the many questions outside o and inside the social networks to operate with engines that my previous model is for the shelf or to be pushed by another machine or a wagon with motor. It demanded to be built again if wanted to use an electric system. The main space where the diesel engine is located should have space and needs more width.

The main axes can rotate and have the distinction of being inside the axes. There is one that allows you to turn at least 2 degrees of help as well as the main axis when cornering. Eliminating the "bush by crossaxle" piece and a turn plate the friction is smaller and allows some spin.

It could work with an engine but for big fans I think it is better to apply two engines.

After this technical data say that it accompanies a minifigure of a machine driver, stickers of the UP company and 8 straight ways.
