T must appear X mins after Y enters the area
This rule will prevent a train "T" from entering the sim until at least X minutes after train "Y" has entered the Sim.
| For example: train Y should take 10 minutes to reach the terminus where the shunter is required. The entry of the shunter can be held until around 8 minutes after the entry of Y so it's available at around the time of arrival. |
