Some really good news from a user on Reddit:
thefishhh on Reddit wrote:Steel Vengeance was testing with 3 trains this morning. They reprogrammed it so they can dispatch early with the two trains. Right now it has to wait until the wave turn until it dispatches. It climbs the lift hill slow until the final break run is clear (which is two different blocks). 3 train ops are definitely showing signs of progression. Id say it will have them by August.
The fact that they don't need to wait for the next train to completely return is fantastic, and three trains testing is good news as well.
