electrified tracks

Post by worldofklaus »

Hi there
is it possible to get the graphics for electrified tracks (and the unifiedmaglev switch as in TTDPatch) for OpenTTD? Will they be included in future releases?
I just switched from Windows to Mac, therefore I cannot use the patch or any *.exe files.

It's not written yet, but it will be someday, but please don't ask me then. I can only say that it will be there when it's done
You will not see unified maglev, you will see 4 types of tracks instead :wink:

Only 4 :?:
What about narrow gauge :?:

because the rail type are stored in 2 bits (4 different values)
if we have more than 4 types, we need to change that all the places OTTD checks railtype and that is A LOT of work
Using the yet unused value for electrified does not need any changes there
Well, it needs the change that diesel can drive there, but that is needed to be coded anyway

Ok, I hope it will be optional (a patch),
For thoses who don't used to play with TTDPatch.

it will not be hard to make it optional and I agree it should
You might want to use it even though you haven't used TTDPatch :wink:

Why not driving a diesel over electrified railway?
Thats a very common situation, at least in Europe.
Even steamers are possible. Using electric locs on non-electrified railways doesn't make sense...

That is what I said. Steam/diesel are type unelectrified and they need to be able to drive on unelectrified AND electrified rails
If there aren't any code changes, but only electrified added, steam/diesel can't go on electrified rails because it's a different type

Will it be possible to add more types easily (with grf files or something)?

It doesn't make sence to have STEAM trains on elect. rails. The steam may damage the wires :twisted:
Diesel ones is also common in the rest of the world.

It shouldn't be impossible since some 'museum'-steamers can drive on electrified rails in reality. But if it damages the wires (I don't know why): It could raise maintainance costs.

The steam engines damaging wires argument has been shown to be, at least in this country, completely fake, and to be due to the railway companies not wanting railtours to get in the way of their nice fast expresses (maximum allowed for steam -75mph, express speed 125mph)

That is NOT a problem
You might end up with some dirty wires, but they are cleaned the next it rains. Besides electric trains removes any dirt it may touch, so it have no problems in getting a good electric connection

What do you mean?

What i have learned in my years studing elektronics... (3rd year at school now) Sparks make the wires more dirty and more resistant, so it leads less currant.* (Spelling) so thats not true if i am not Completly mistaken.

You are partially wrong. In an electronic circuit, sparks cause a part of the PCB to melt ever so slightly and coat the metal components, this can lead to poor contact. Sparks can also cause solder to melt and the resolidify as a bad ('dry') joint. When two components are moving over each other, sprung together, and with over 1000V passing between them, the sparks merely vapourise any dirt (they are hot enough to vapourise carbon which is around 4000 degrees C at the core), and as it isn't in an enclosed space, the dirt vapour is blown away by even the slightest movement in the air (such as the convection circuit above the spark) and so do not reform over the wire). If you want to see an example of this in action (on a smaller scale), compare the performance of a model railway after it hasn't been used for a few weeks with that after 8 hours running (where maybe 0.1% of the energy has been put into the rails, than is put in by 1 reilway electrification spark.)

or check out an electrified railroad when it's a bit foggy and freezing (below 0 °C). The fog will touch the wires and freeze instant. Since there will be a tiny distance between the train's pantograph (is it called that in English too :?: ) and the catenary. Sparks will then jump and you will see a nearly blue light when the train drives. The next train will do the same since more ice have packed on the catenary
They don't replace the catenary each time it have been cold :wink:
