I figured out how to build a Lego train that could bend in the middle like the LRT trains can. Here's what I did.
1. First I built two train cars without bogeys at both ends
2. Then, I put pieces that have bumps on the side and attached pieces with holes in them, to those pieces.
3. Then, I put connector pegs in.
4. Next, I put an elastic in, connecting the cars together, and then I put more pieces wiht holes in them over it to secure the elastic in place.
I got this idea from looking at a Lego C-Train at the model train show a long time ago.
This is a Duplo Easter egg machine my brother and I made, and I made it in 2015. The Easter eggs get dumped off a train down a ramp and into another train.
