How far ahead of schedule are railtours typically announced

[Zander trains]

So I was looking at what railtours are coming to my area for the rest of 2024, and it doesn’t seem like there is much.
I was wondering if anyone knew if there is a chance anymore will be announced for later this year and how far in advance they are announced.
