Could be a few reasons. I think the most common one is having a node that isn't actually connected, but looks like it is. Trains also take the shortest path, so if the dam is on a longer path, it won't work.

trains won't cross it for some reason, any idea why?

no a bugs in

My train tracks are vanilla. I haven't checked the nodes and I'm not exactly sure how to do it. I haven't had any issues with the nodes on the metro dam.

@French_Bread Out of curiosity, are you connecting it to the vanilla train tracks? Or do you have modded tracks connecting to it?

Something to check, make sure your nodes are actually connected. There have been various bugs that can cause nodes to not connect, when they look like they should. If you have one of those where the dam is, then the pathfinder just sees two dead ends, not a continuous path. So nothing is ever routed through that path (across the dam).

Correction: I meant I don't have the monorail DLC.

For some reason I can't make train routes across the dam. It's weird because the metro dam works great. I can't test the tram dam because I don't have any DLC. Is there a special way to connect this dam that differs from the metro dam?

@tippyc Great!

@Shaddorry Ive never used MOM, but I could do one with the new vanilla above ground metro

there should also be one that's MOM compatible with metros.

That slow river/Creek that you hope to get power from will simply build up till it trickles over or around the dam. The depth of water behind or in front of a dam will simply make NO difference whatsoever! It must have a steady feed / Supply with plenty of pressure. When you go to draw a dam in the game, Pay attention to the flow of the water{the little arrows in the river/ also to the dam it's self under the mouse, it's MW's indicator. You'll see it showing how much the current flow will produce in power. That's NO guarantee if that water flow is to slow. You might be simply building a lake!!! With ZIP for MW's output on A DAM

@tippyc Good day, I would Like to bring a slight correction to your remark regarding dams and water height. If you have a lake for-instance that's a man made lake and has little or no water flow, A dam will hold the water and keep from flooding low lands. A power dam requires FLOW, and plenty of it! If you have a deep lake that's held back with any dam that's made for power and there is no flow. It will NOT produce any power whatsoever.. in the game or real life! At 1st when you build a dam in the game and it builds up water behind it. If there is NO feed to the water if will STALL and not produce power.

I use dams as current generators with very high currents instead, but they do work, but not with hydrostatic pressure, has to be dynamic pressure. If there is enough water flowing into a dammed lake, it does function. Lake has to be a certain size to get the full potential, however.

@caseyas435943 Dams only care about the difference in water height on both sides. If the drop is large, you get more power. Not all maps have rivers with enough elevation change.

Sadly a dam never much works of 99% of all maps. You'd think you build one anywhere. And once the water fills behind it you get power. But no. You could have a lake behind a dam taking up 90% of the map. Water coming through a tiny point your dam and you get power. But no. Sad too. A fun idea which doesn't really work in any way shape or form.

@sammyson9 Thats what I was wondering. I thought it should have been easy to find, but there was nothing.

why has no one done this before
