This is the world fastest toy train of this size (as far as I know) reaching a scale speed of 485 Kmph. The track gauge is 66,5 mm compared to the 1435 mm of the French TGV, so it is faster than the TGV when it is carrying passengers. The entire track is banked at 45º which gave me some issues on the straights but I wanted to avoid the jumping that would occur if the banking transition was too sudden. Making the track was a challenge on itself and making those straights straight took way too longer than expected. I ended up using rope to set a straight path to follow when laying down the track brackets and of course I hot glued everything to the shop floor. The biggest limitation with this setup is that in the straights the train keeps derailing because the banking is too high so I'm already thinking of the next iteration because I won't stop until I need to make a shield to protect me during testing. If you have any knowledge of any real toy train record please let me know in the comments.
