Number of trains on route to single station limit.

[irbork]

TL;DR

The idea is to have slider or circuit signal that allows to limit no number of trains en-route to that station.

What ?

The perfect solution in my opinion would be if the value of station enabling signal would also determine how many trains can be on the way to that station at any moment. If the signal is constant "green" value 1 than only one train will be permitted to go go that station, another one will be dispatched after there is no train on the way or on the station.

Why ?

It will greatly simplify station design and overall train network load.

It would be useful if it would not overcomplicate routing.

This has already been suggested in the following thread:

Instead of the game allowing the player to set a specific limit on the number of trains enroute to a particular station, I think it would be best if this were controllable by the player with a combination of circuit network and conditional train orders.

Here are a list of threads related to implementing conditional train orders into Factorio:
