Eh, the classic Gundam is around 18 m tall. This comes close at 12 m. The upper body and arms certainly invoke mobile suit aesthetics though

It reaches 12m on a telescoped crane, the actual scale of the robot body looks pretty small, smaller than the cab of the truck. Pretty human scale all things considered, makes one wonder if it's goign to be mounted on treads or legs one day for indoor use. It does look very cool indeed.

[bobthepanda]

in the context of a train line, you may not want it any taller, since there are things like overhead wires to deal with if it gets any taller.

[krisoft]

I don't think the argument is that it should be bigger. Just that if it's not enormous we should not describe it as enormous.

[jncfhnb]

Perhaps this can serve as just a single leg of a larger combination though

[ThrowawayR2]

The AV-98 Ingram from the Patlabor anime is 8 m tall, so I wouldn't count this robot out.

And the Knightmare Frames from Code Geass are around 4-6 meters tall.
