Here's the idea. Really, you don't need a blueprint, anyone with any basic knowledge can do this from scratch and achieve very high SPM. DIY is always more fun than just pasting in someone's BP, which rarely I find satisfying unless it's a nice rube Goldberg circuit invention.

No belts, bots, chests used.
Train rotates through patches and loads enough raw resources for all science in *each* wagon. Mostly waits at iron and then copper, with about 1/5 of the time at coal and stone (to get the ratios right). They then proceed through a series of steps where raw resources are removed from the wagons and replaced with intermediates necessary for the entire science build. There is no interaction between wagons in the train, each wagon is a self contained unit.
As you add production, you can copy/paste the assembly line and expand downwards.
I have just gs/rs in the image above, but you'd have stops on each line for: plates, gc, gears, belts, inserters, red science, green science, steel, pipes, rc, engines, sulfur, blue science, sticks, rails, modules, bricks, furnaces, violet science, bc, red engines, batteries, frames, lds, yellow science. rcu. jetfuel is all fluid so mabye not train fed. white science you'll want to pull and deliver to the labs like any other science.
