This man attempted to break the world record for the fastest LEGO train with a homemade creation.
Believe it or not, the record for the fastest LEGO train saw it hit a top speed of 29km/h (18mph).
Not too bad for a small plastic toy, right?
But one YouTuber – and LEGO fan – in Germany recently decided to challenge that record.

He built the remote controlled LEGO train from scratch
While LEGO is a staple part of millions of childhoods across the globe, the colorful plastic bricks aren’t just for children.
Last year, engineers from McLaren made this life-sized, fully-drivable McLaren P1 and LEGO Technic recently revealed a Chevrolet Corvette Stingray set.
Meanwhile, Lucas from the Lucas-Dynamics YouTube channel, regularly puts his LEGO building skill to the test.
In one recent challenge he attempted to break the world record for the fastest LEGO train – meaning he’d need a top speed of more than 29km/h.
His first attempt came in at just 7km/h (4.3 miles) and prompted Lucas to change the gear ratio, which boosted it to 8km/h (4.9 miles) – an improvement, but still nowhere near enough to claim the title.
So, Lucas fitted a much faster motor to the small train and gave it another shot, which yielded much better results and a top speed of 19km/h (11.8 miles).

Yet another rebuild beckoned, this time Lucas added in some bigger wheels – twice the size of the previous ones – and headed back to the track, which had to be extended to accommodate those super-sized wheels.
With that done he let the new – bigger wheeled – train loose and it managed to just nudge above the record and clocked in at 30km/h (18.6 miles)
Unfortunately, it was so fast that it ended up derailing and crashed to the ground in bits.
He then swapped out the double-sized wheels for ones that were only 1.5 times larger than the originals and – success – the train hit a top speed of 33km/h (22.5 miles) and managed to stay on the track.
