Constructing scissors crossovers still touchy

[Dr. Funkenstein]

Hey, first up I've got to say congratulations and thanks to the devs for staying committed to ongoing development and bugfixing. First time I've booted up the game for a while and construction and road upgrades are so much simpler.

That said, I've found constructing scissors crossovers to still be quite difficult at times, "too much slope" errors are far too common.

Anyone got tips for this?

Ideally always build switches (including crossovers, crossings, slip switches) on perfectly level track. As in, lay the through routes with the alignment manually set to level, not auto-aligned to terrain. It doesn't completely eliminate issues with complex trackwork, but it certainly helps in some cases. Looks better too, since switches on sloped track is something the game handles very poorly.

The game handles it very well, but it just really wants you to stop building roller coasters. As per above, keep station approaches and any junctions level. When you cross tracks on a slope, even if works, it will look absolutely awful, especially in cab rides. When you cross tracks and it goes dark during construction before you click the tick, it means that it’s not level and it will look horrid.

You can eliminate double crossovers by changing track designs. My mainline tracks only have single switches; if all train tracks are laid out as a collection of fiber bundles then double crossovers will not be present.

I am not a fan of double cross overs myself, so I build busy freight approaches in various other ways. Also, they are not very common in the real world, since they are expensive and hence only used when there is no alternative.

However, the occasional crossover can look quite nice

On occasions i was able to solve this error using the N/M keys to adjust the horizontal profile of the first cross track to follow the terrain more closely. The second cross track then snaps to it more smoothly.

In TpF, as in real life, junctions should ideally be on a 'plane', that is a flat surfece. That could be but needn't be level but should be on a consistent gradient. So in areas where a junction is envisaged lay your initial tracks in the immediate vicinity with a fixed gradient.

When I started constructing a large train station in the largest city, I wanted it to have a main station look with both a huge station itself and many tracks on both end that give this passenger hub vibe. The scissor junctions can be tough to create, especially when two cross each other halfway. It took me a long time and patience to create such a marvel, but now I'm quite adept at it.

I just got a crazy idea for avoiding double-crossover. If you have a straight running line sharing terminals with a curving line, then you might be able to limit to one shared track, and two parallel non-shared tracks on two sides of the shared track. The kicker is that you make the train on the straight line to drive on the wrong side of the track to make sure trains on the shared track have the same direction of travel. When the curving line departs you only have a single Y shaped switch instead of the double-crossover.
