MarloweBricks

I went with LightMyBricks. I have 4 or 5 modular buildings lit up now and lighting kits for 5 more... once I get the sets built (I am behind!). I also use their products to light my creator cars and a passenger train. I am now working on a DIY hybrid where I use their connectors but my own LEDs. Once I learn where to post it on Eurobricks, maybe I will write a review going over how I did it...

I also print my own track. I can use CAD, but instead I bought a membership from 4DBrix and download their designs. I pretty much just stick with elements that TLG does not produce, for example I am currently printing myself Wye-Switches. I am also working on printing a new car coupler... I don't want to go into more detail until I have a finished version to show off. But is there a place here to talk about 3D printed parts for use in LEGO builds?

I ran into the same problem when I went to ballast my R56 curves. I started with L-Guage's guide lines, but then slowly worked through 4 or 5 revisions until I found a solution I liked. I uploaded some photos of how I did mine (track is from Bricktrack's): http://marlowebricks.com/2021/10/06/ballasting-r56-curves/

I needed more weight over my drive wheels and only had 2 boat weights, which were not enough. We bought BB's (for a BB gun) and put them in a small bag - this added to the boat weights worked out perfectly for my needs. All of this, plus the battery box and IR receiver are in a MOC tender that hides the drive wheels. It pushes a customized Emerald Knight steam engine and pulls 6 passenger cars.

This is what I did. I built a list of parts in a Bricklink wanted list based on reading through the instructions and then removed the parts I already owned. I then went through Bricklink and bought the parts I needed. I made the same car they offered in the instructions, but 4 studs longer, I believe. I did a double wheelset on either end and skipped interior for now. Ended up with the original car and 5 MOC cars. Looks pretty sweet going around the track.
