S-Bahn

[Saskia]

Hi...
what about add to the project the s-bahn?

Saskia explained me what the S-Bahn is (I don't know if I really get it) but:

If we want to start a S-Bahn project, what would be needed to draw/code. Are there only trains needed or are more 'thingies' needed?

Oh, so it's trams now ... for S-Bahn you would only need some suburban stations and few new vehicles.

For trams you could see the screenshots of Locomotion ...

[John]

you guys have weird s-bahns,
in munich its the ET423, great train. (i used to live there)

oh, i c u also have the 423 in koln.

I can draw graphics for trams but is there anyone which will code it?

[whitehawk]

There could be a maintenance train for railroads. Or something like the road reconstruciton in towns.

Any follow-ups on this? Trams would be really cool to see implemented.

What is the s-bahn?

The S-Bahn is a short-range train in the DB railway network that connects max. three cities. Especially used in big cities with many villages or other cities around it. It's something between a tram and a regio-train: you can use it with your tram ticket where a tram ride would take too long. The stations are everywhere in the city, mostly built on bridges.
In Cologne the engine is a BR 111 or 143 or 146 combined with regio or special S-Bahn cars (like in my sig) with even more entraces (three per car) or a BR 644 ("Talent") or 423 ("Regiosprinter").

I add:

Schnell Bahn, "fast railway", but it's a suburban railway. Usually with fixed lines numbered S1, S2, ... normal trains are used.

In Spain there are the "Cercanías", C1, C2, ...

In Rome, FR1, FR2, ...

In PAris, the RER.

Other ideas?

A totally new graphic engine...

It seems that there's no-one which wants to code it.

IMHO the developers are busy with multiplayer coding...
but after...

coding trams wouldn't be that hard at all, just a lot of work (since it requires a new kind of tile)
but the worst problem is the graphics, because the tram network would require some 40-ish sprites or more.

[Purno]

40-ish

huh??? what's that?

[spaceman-spiff]

40-ish

huh??? what's that?

-ish means 'about' (ongeveer)
You can use this -ish with every number

[Purno]

but the worst problem is the graphics, because the tram network would require some 40-ish sprites or more.

I think that can be done. It might be not easy and it might be lots of work and it might be not very good result, but it can be done.

EDIT: We need:
Tram rails on roads
Tram rails on grass (or something)
Tram stops
Tram depots
Something else I probably forgot

if you use the trams you must sacrifice one of the rail systems because the ID of the rai systems are a 2 bit value (0=railroads, 1=monorail, 2=maglev and 3 nothing or electrified railroad if the developers want to keep all tracks simultaneously) to use new tracks you must use a 3 bit value which permit 8 different tracks or 4 bit values (16 tracks)

That's TTD Patch, this is OpenTTD, that's different? Isn't it, am I wrong???

in ttdpatch you must sacrifice one type of track
i have read somewhere that in ottd is possible to change the store value which means that you can have as many tracks as you want, but i'm not sure

[mnorman]

In OTTD you would have to sacrifice one of the four track types to allow for trams.
In TTD patch you have to sacrifice one of the THREE track types to allow for electrified railways.

there is probably a way to allow more track types (I would want HSR, narrow guage, and rack railways, as well as trams), but this would include changing the code every time it refers to the track type (probably a huge job)

which is why I said it would be a lot of work.
trams aren't worth sacrificing a railway type, the system already needs an overhaul to allow more tracktypes one day (if we add 2 more bits it's already 16 types of track...) but yes, it would be a huge job.

[NCarlson]

Firstly, it would be much better for trams to be a new type of road, as they have both directions in a single tile. This introduces new problems, but I think it would be better to add trams as another road type (that can be built on top of standard roads as well as on their own) than to have them as rail. This would be helped A LOT if a way to have diagonal roads is found, althogh I don't think anyone should count on that. If we have four rail types available now somebody should probably start workinf on graphics for narrow gauge track and trains. In game these would be cheaper but slower and have a lower capacity than standard rail. I see no reason for a seperate high speed rail type as speed penalties for various construction on standard track is IMO good enough, especially is high speed trains get a penalty for grade crossings.

[Purno]

Indeed. Trams have the same system as roads.

But if we place tramrails over road, we can have lots of graphics.

Like a road crossing with:
- a tramtrack straight ahead
- a tramtrack to the left
- a tramtrack to the right
- a combination of those
- rotated

So a better idea is to draw the tramrails as transparent sprites which will be placed over roads by OTTD, this way you reduce the amount of sprites, and you can use tramrails sprites over roads and over grass (and other terrains).



But can tramrails be connected to standard rails?

[Lilman424]

maybe not to normal rail, but be able to have trams off the road
