so i love the mod, but i find it odd that u can't even use them as soon as u can research them cuz u need LDS to make them even tho that is after chem science but u get them at the same time as normal trains at green science

Electric Railway 1 (which is the initial tier) needs Railway (red + green), Batteries (red + green), Electric Engine (red, green, blue) and Low Density Structures (red, green, blue) before you can research it. For the actual research, you only need red and green but it will not be available to you unless you have all the prerequisites.

I am not sure that you can research Electric Railway before you have all the prereqs, unless you run some mods that change the technology tree.

oh okay sorry then might have been some other mod that enabled them earlier than it should
