I've been thinking of building a LEGO Transformer train for many many years now. Back then, what stopped me was the bar I set myself: I wanted it to make use of LEGO 9v train motor feature (below) and this means the train must also make use of LEGO train axles/wheels too (chunky 6-stud long piece ).
The LEGO train motor above is pretty heavy and if implemented in my MOC, the robot mode's gonna be very heavy and barely poseable.
About 3 months ago, this project started life from an eureka moment . Initially this would be my LEGO Astrotrain, then changed my mind weeks later because I wanted to build Astrotrain in the future as a steam locomotive. Below are some of the criteria I'm firm on before I start building:
- Each segment of the train must be flexible /able to swivel to some degree like a typical train to negotiate bends.
- Absolute focus on making the train mode as realistic as possible and the shuttle mode as second priority.
- It must be primarily white.
- This project /Transformer remained nameless for 2 months before I decided on "Railrazor".
- It's my habit to build the robot head last, so I was worried how I can cram in the head with my current design. Thanks to google I discovered something called pantograpth. :)
- The weaponized train mode for the middle segment was incidental. There were some hollowed space inside the train. While not cram in a few weapons inside to be flipped out, I'd thought. :)
- The final color scheme was undecided until I referred to my available hinged bricks.I have much more blue and black of these hinged bricks compared to other color.
- I blew 2 balljoint socket bricks from constant test-transforming him between modes. RIP dear bricks.
- The wheels used here are "faux" train wheels made from 2x2 round plates with axle hole. They're not compatible with LEGO train tracks obviously.
Side by side with LEGO 4560: Railway Express, my first LEGO Train which I bought the same year I got out of my dark ages.
Weaponized Battle Mode
2 missile racks guarding one side, and 2 cannons guarding another
... and finally, a dual barreled rifle on top.
Transformation to Shuttle
Due to the heavy panels becoming the shuttle wings, they sagged a lil.
Oppps! Forgotten to implement landing gears to prop up the shuttle nosecone. I have to build a separate scaffolding to hold it up for photoshoot.
Those 2 guys were commuting inside the train but suddenly "ejected" out after it decided to transform into a shuttle.
Optimus Prime persuaded Railrazor to join Autobot cause.
Are you ready for Part 2? Let's go!
