Describe the issue

With a block brake directly behind close to a station and trains longer than the station (via cheat) that reach beyond that block brake, a ride will initially start with overlapping trains.

See attached park.

In general, the handling of block lengths shorter than train length works fine, and a track "fills up" leaving approprite gaps. This case here seems to somehow circumvent that logic.

Also: When the ride is running, everything works as expected.

Steps to reproduce

Not sure exactly.

• build ride with block brake directly touching the back of the station
• use cheat to have trains longer than station
• see trains overlap when starting ride

I've seen it happen with a block brake close to but not directly touching the station as well now (thanks, @astraylife1).

I figured out a reduced testcase: It seems to be caused by the block brake directly touching the station.

I've updated the issue description and steps to reproduce.

I've noticed this as well. It isn't inherent to touching the station. You are using a cheat to make the trains longer than the station allows. So when the game spawns the vehicles, they may overlap if the trains are so long that they overlap the preceding block brake. The ride will correct itself once you cycle the trains. I wouldn't say this is a bug but more of a result of using cheats. And the said cheat used even gives a warning tot take extra caution.

[cheweytoo]

Well: If the block brake does not touch the station, trains don't overlap and an appropriate amount of block sections are skipped when filling the ride with trains, even with "long-cheated" trains.

Same as when block sections are shorter than trains, which can and does happen without using any cheats at all.

I just tried it and was able to get the trains to overlap using one straight track piece between the block and the station.

Oh, interesting. Yes, so have I now. Weird, that didn't happen in my initial tests. Time to update the bug description. Again.
