Well, why not combine both versions? We can only have 8 bridges, no need to waste a slot.
I have already explained my reason for doing so. But to reiterate, Locomotion paints a slope like this:
2. on top of that the base tile of a straight bridge part.
3. on top of that diagonal filler, for instance bricks to fill up the brick bridge
4. and finally on top of that the sloped bridge part.
This works great if for brick bridges because they're solid and step 3 hides step 2, but it really produces awkward effects when the bridge (like this one) isn't solid.
This is how the concrete bridge would look if it was just one file:
Cheers. I'll keep fiddling with it until I get it right. Expect an update tomorrow.
I think we need to limit the use of super speed slopes in some way. Mine for instance, only work on ground level. Also, if you make it too much like another bridge but with slopes, then it completely negates the other bridge.
One of my reasons for making this bridge was that, although I like the girder bridge, it often makes a visual mess, making it hard to see or place signals or manipulate tracks above or below it. So, yes, I grant you that from my point of view the concrete bridge replaces the steel girder one.
I will make it more expensive to start with (I'd appreciate your input with regards to the pricing) and will limit the slope speed somewhat (again I will appreciate input).
