Hello,

our latest moc train-base, we tried a 0-10-0 and it works fine in normal lego curves :

 

Unless used on R120's, that's not going to work. Your current set up is F-B-B-B-F, which makes it impossible to take R40's and switches (and frankly, as I said at the start of the comment, only R120 will be possible). Now if you'd change the set up to B-F-B-F-B then you're in business

Very nice job @brick-builds! Like a tutorial.

Nice presentation in the video, as always! However, I would echo @Barduck's concerns - in my models I've found a wheelbase of 13 studs between flanged drivers is already pushing it when going through standard LEGO R40 points, so I don't have high hopes for the 17 studs of your chassis here. Putting the flanged drivers one axle inwards as @Barduck suggested would reduce the wheelbase to 9 studs, which would go through curves far more comfortably (although with more overhang at each end, of course).

Do you plan to build a loco with this chassis, and if so do you have a specific one in mind?

You can use also B-F-B-B-F-B (yes six axles) but as @Barduck said F-B-B-B-F make impossible to take R40 and switches

Thanks for your comments I´ll try out your tips this afternoon and write an answer here.

Sorry for the late answer. We tried some different setups and here is the result:

Very nice, good to see some scientific testing here!

My instinct tells me that as you add the weight of a loco on top, the longer wheelbases become less and less happy to make the "jump" over the checkrail on the points - maybe something for your next video?
Just placing the battery box on top of the wheels rahter than it's own cart will give you a good head-start, and you could see how many extra weight bricks (or just anything heavy tbh) you can add with the motor still propelling it through the points.

Then, for comparison, we need to know how heavy some train MOCs are... unfortunately I'm at uni so don't have any to hand, anyone willing to weight their trains for Science?
