Railyards and freight movment

Thank you

For example:
Berlin prio 0 and then 1, 1,..., 1, 1, 2, 3, 4
While the 1's aren't being used (except for maybe an airport and a unit here and there)

Yep, that is the general gist of it. The incrementing depot priorities direct the overall flow of freight.

When I build depots, I press the 'L' and that enables the map-factory overlay.

I look for the hexes with rail-yards and only place depots in those hexes, unless I have no other choice.

>> are trains from a RY 2+ used when there is no depo (which is being used 1-4) in range (30 hexes) ?

I don't think so.

But that should never happen, because...
- Every railyard within 30 hexes of a national supply sources is used by the national supply source
- Every railyard within 30 hexes of a depot that supplies a troop is used by that depot
- And when your troop are far away from your national supply source, you should build intermediate depots between a) the national supply source and b) the depots that supply the troops.

Those intermediate depots work best if they are more than 30 hexes from any troop that needs supply (else they might accidently supply that troop and use lots and lots of trucks to do so).

And for optimisation: place those intermediate depots on an airfield and place the transport planes on it, so that you can lift freight from those intermediate depots to a depot at the front that has an airfield (or a unit on an airfield, but that's rare; either way, try to avoid lifting freight to a place without an airfield).

Thank you both, very helpfull info

even if you don't think you need, you really do.

there will be intervals where the freight does not have enough SPP left and will have to look for the next closest depot, along the path, until next turn.

it depends how the train is used.

by design, freight doesn't retain the 'train' so all the discussions in the other thread

units do, till you detrain them and that allocation is indeed deducted from a rail yard somewhere.

Is it easy to find the relevant railyard - no as it could feasibly be a combination in the 30 hex range but a good test is one of those turns when something like 2+ mot/pzr divisions turn up at Berlin. Usually they will grab their trains from the Berlin hex and this will have less trains for a couple of turns till those units release their trains

yes, railyard size (& thus train production) is independent of depot status/existence

30 hexes is excessive as a minimum, I reckon >10 disengages a depot from immediate unit supply - this assumes a decent front line depot network so its situational
