m00se Posted March 29 Posted March 29 (edited) About a year after my first roller coaster (https://www.eurobricks.com/forum/forums/topic/197576-moc-roller-coaster) there is now v2. Widened the track from 7 to 9 which gives a bit more flexibility which came in handy especially for the lift. Still limited by the fact that you loose a lot of speed quickly, but at least I managed to get an inversion in as well as to get the trains around the track without some extra help. Started to run out of certain parts, but I also began to run out of table anyway ;-) There actually is a car in this picture: Transfer track. Underside of the trains is rather simple, but after many attempts this turned out to be the most "efficient" (in terms of keeping speed) solution.

Carsten Svendsen Posted March 29 Posted March 29 (edited) I had a dream once of building a roller coaster too, but I could never figure out how to make the most important thing - the train. The wheel base was simply too difficult at the time to achieve. Your design seems to be lacking as well, I'm sure you can improve on it somehow to not lose out on so much speed. And in this day and age, we have so many micro-pieces available, that I would be surprised if there isn't a solution hiding somewhere. Edited March 29 by Carsten Svendsen Quote

Complicated does not seem to work better, this fairly simple design worked best. Make sure to have you top wheels to roll extremely smoothly. Bottom wheels only add friction, so here it are only pins so they don't actually touch the track (except for on the lifthill where in this case it's obviously needed) Quote
aeh5040 Posted March 29 Posted March 29 Amazing construction! It seems to be catching somehow at the bottom of the lift. Quote
