WW Category 1: Jupiter & #119

Both these steam engines participate in the Golden Spike ceremony, a re-enactment that takes place every year and celebrates the completing the the United States Transcontinental Railway.

Jupiter (on left) and #119 (on right).

These are the real steam engines:

Both steam engines mocs are built in 7-wide scale, and are PF powered. Each of them utilizes an M-sized motor which is mounted vertically inside the cab. Both the Jupiter and #119 tenders' house a rechargeable battery and an IR receiver. The batteries for both engines are neither stud mounted nor used as a structural component, and can be easily accessed for turning on/off or recharging by the use of a combination of removable panels and hinges (#119), or a lift off car-body (Jupiter).

Although they may look similar on the outside, both Jupiter and #119 are built using almost completely different designs. Besides their obvious differences in shape and dimensions, the engines are different from each other in their cab construction, boiler internals, wheel spacings, M-motor mounting, leading truck attachment, and the methods used to hang the pistons.

Interestingly, the construction layouts of the two tenders have an even greater level of dissimilarity from each other the then engines do. This is mostly caused by the difference in brick shapes that must be used in order to give each tender's distinct paint schemes some accuracy. The cascade effect stemming from the paint schemes 'shapes' is that mounting points for mechanical items cannot be located in the same spots on both tenders. Hence, each tender ended up needing a completely different build design to enable accessing of the battery box.

One thing that I wasn't counting on when I started building this moc is how many Lego parts that exist out there that still aren't available in dark red. That made this build a much tougher challenge then it otherwise would have been.

More dark red, Lego!

both great trains with nice colors. I like the Jupiter better, the colors on it remind me of old Lego system sets.
