Help Needed - Stone Quarry not producing enough stone

[Flip]

Summary
I have a long chain to supply a construction factory which supports 4 cities however the stone quarry supplying it is only producing 100/400 and is collapsing entire chain.

Long Version
The setup I have is that I have a stone quarry north of my map (Large Map). That connects to a Dock (Dock A). I then have a line (Line A) where I use ships to ferry stone down to a Construction Materials Factory at the bottom of the Map, they drop off the Stone at the dock there (Dock B). They then pick up the construction materials and ferry them back to Dock A.

I have a second boat line (Line B) that then transports the construction material from Dock A to another dock along a fork in the river (Dock C). From here on the construction material is transported to a city via trucks. (Note: Line B then picks up Oil from Dock C and transports it back to Dock A).

This was working great until I noticed that the quarry producing stone was only producing stone at 25% capacity (100/400) and my ships on Line 1 used to be ferrying 130 stone per trip where now only doing about 90 per trip.

As such I connected some cities down south to the construction factory and ran some truck lines there to supply construction material to them (cities that needed it) hoping the high new demand of 3 cities would kick start the stone quarry to start delivering more stone...nope. Now the entire network is collapsing because I cannot supply enough stone because it is siting at 100/400 production capacity. It's Transport Capacity is at 100%

I have checked and there are no other sources of stone contaminating the lines and none of the cities have close to full demand met.

Anybody have any idea why this stone quarry is being difficult?

The key to this is the con mat plant, what does the customers tab of the con mat plant say - which customers have recently been supplied ?

One is shipping 75 Units and at 23% shipped (that's the Boat Route). Something was wrong for some reason with the truck lines, one is showing 23 units shipped at 100% delivery, the others are sitting at a few units shipped and no delivery stats. I have re-jigged the truck routes and will see if it starts wanting to ship to them correctly

Sounds like it needs to level up and the transport % is too low.
There are 3 grey/blue bars on the main tab. If any are grey it won't level, but when they each hit the line on the right they go blue. Once the plant levels, it will increase demand, which will level the quarry (same process as above applies) and enables higher production.

Hi Lemming3k, I can see that Production and Shipment are at 100% for the factory (in Blue zone) and Transport is at 71% (in Grey zone). Any suggestion on increasing transport so I can level up the factory?
Road lanes are at 100% transport but sea lane is at 53%. I could increase it by adding another ship but profits will suffer as there will be no stone to transport from A -> B, it will just be Transporting from B -> A

So I added another ship (which is making a loss) but it seems to have moved the shipping up enough to upgrade the factory and now I have 200 stone. Still making a loss due to the third ship that doesn't have enough to transport though.

What is the line rate for the sea route? If 75 units are being directed towards the town from the plant then your rate needs to be just above that number to carry it all - so yes adding a ship or two may be required.
It's hard to be 100% without seeing it all but sounds like bricks could be piling up at the dock and possibly being wasted if too many are stored.
Once you're above the rate needed then it just takes a bit of time to catch up (the transport % isn't updated until a delivery is made).

Always remember the factory decides where to ship goods, so when you add an alternative it could alter your existing line demand, and you may need to wait for the factory to level before you can supply multiple cities 100%.

EDIT: Sounds like you've got it solved. If the sea route is running full (even just one way) then it should make a profit, but yes, if partially empty then it could be a minor loss. Ship rates can be hard to balance due to their large capacity.

Just want to say thanks to all on the thread, increasing my sea transport allowed the factory to upgrade and solved the issue. Thanks for all the advice!
