How do I connect actors following spline?

I did spline following platform that acts as a train cart but now I want to have a few platforms like that connected together. I tried using constraint and placing three platforms at different starting points and moving them at the same time but it didn’t work too well.
I tried looking for some way to connect them together but found none.

The timeline curve is from 0 to 1. 50 is the distance between the platforms. You can set rotation the same way.

Thank you, works perfectly!

Do you also know how I could set start location of all actors following that spline so that they don’t start in the same place (inside each other)?
I tried using New time but it more broke than fixed things.

Something like this maybe?

I tried it but everytime the Timeline starts playing it sets all carts to first point in Spline so they always are in the same place.
I thought that it might have been something with changing the timeline settings but it also failed

Yes, you have to adjust the timeline too. For instance, if you have 3 platforms with the distance of 100 units between them, you need to add 200 to the first platform location and 100 to the second, just before the [Get Distance Along Spline] node.
