Describe the Suggestion

This is not a suggestion in itself but rather an overview over what suggestions have been made multiple times in relation to trains. For example for movable train tracks / turntables / train lifts there are currently 9 issues that more or less suggest the same thing. This should (hopefully) help close those duplicates.

Movable Train Tracks

Open issues: #3201, #3211, #3288, #3377, #3398, #3681, #3826, #3953, #4583
Suggestion: Train tracks should be movable as part of contraptions to allow the build of turntables and train lifts
Although this would be an amazing feature this leads to pathfinding issues and train schedule issues and cannot really be implemented with the current way of dealing with pathfinding and schedules.

Redstone controlled Train assembly/disassembly

Open issues: #3265, #3434, #3442, (#4814)
Suggestion: Trains should be able to be assembled/disassembled using a redstone signal (similar to cart assemblers)
This should not actually be that hard and together with Computer Craft you can already control assembly and disassembly.

More bogeys per car

Open issues: #3261, #3462, (#4528)
Suggestion: Cars should be able to have more than two bogeys
This is also a nice feature as there are articulated cars or historical cars like the three axle Umbau-Wagen. The only problem is that in the real life the turns are in no way so thight like in Minecraft, which obviously would derail three axle cars and the like.
