This type of junction is good in the respect that it has a high capacity, but it's no good for hilly or cluttered areas because of the large amount of land it requires.
Broken down trains only affect the one track and left turns.
|Split Before Merge||No|
- Can handle 4+ trains at a time.
- Takes up a large amount of space when built without sharp corners.
- Make the loop and diagonal branches longer than your trains, so the main line is not blocked by a waiting train.
- Use tunnels if the bridges slow down your trains.
- If necessary, upgrade to an Over-Under junction.
- Area: 10 x 10
- To be able to fully store a 12 length (6 grid spaces) train in each left turn movement, use a length of 2 for each side of the cloverleaf and start the cloverleaf 3 spaces away from the center intersection
- In general, the storage space of each cloverleaf is 7*n for a size n cloverleaf, where n is the length of each side in the leaf (start size n cloverleaf at 2*n-1 spaces away from the center intersection)
Cloverleaf junction with tunnels instead of bridges
Tunnel cloverleaf with the corners on the inner side rather than the outer side of the junction.
