This is the instructions I have made of a Union Pacific Big Boy by Knud Albrechtsen
Inspired by Jayhurst
I have changed the design to work with Power Functions instead.
This means that the tender had to be redesigned.

Updates:
2016-07-27: I have made changes to the train boogies as well to make it run corners much more smooth than with the original desing.
I have also made changes to the sides of the boiler to make it look more like the original train.

Instrutions to download and use the partlist can be found here .

As it takes a lot of time for me to make these instructions, please make a donation to my paypal account to insure the further development of instructions on this site.

All instructions are created with LDCad, LPub3D and the LDraw Library of Parts.
