double tracks

Double track splines are not a good idea, too many problems with them. Better to use two single tracks, placed side by side. There are several guides available on the DLS to help maintain the correct spacing. Some are visual guides and others are object you attach the tracks to in order to keep the spacing.

Tracks have a direction. By using two singles, each placed in the correct sense, placing signals is easier and the AI is less likely to become confused. Single tracks can also be straightened, a big plus, and turnouts can be inserted. :)
 
Also you cannot use the replace tool on Double Tracks. So in the future if you ever wanted to update the track and don't want to manually replace every rail spline, better and easier just to use single.

I use double track frequently and do not have an issue with it. It is great for long stretches of plain line. Sometimes I need to use single track when installing switches in particular at complex track locations. No track has a direction. You can lay it in any direction you feel the urge. Nor is installing signals on 2 single tracks any easier or harder than double track. And finally if finally why do you think Trainz provided direction markers if track is directional?
 
Oh you can place tracks any way but they do have an internal direction. Place two set of single track side by side

]===============> a
]===============> b

<===============[ c
]===============> d

] is where you start
> is where you end

If you use the a-b set and place right-hand signals on the tracks, you would have to rotate the ones on track "a" to get them placed correctly on the outside instead of having half between the two tracks.

Sure you could use left-hand signals on track "a" but you can't tell by looking at the track what its direction is. If you place a track marker on the track, it will point in the direction of the track but that means having track markers everywhere. This is also what the double tracks look like. Both tracks facing the same direction.

On the other hand if you always place double tracks like c-d, then there is no doubt as to which is the direction of the track. Naturally if you have left-hand running trains, you would switch the locations of the tracks.

Wow!

The fact it can't be straightened is issue enough. The fact it can't be replaced is issue enough. Don't use it, the time it saves in laying is simply not worth the cost in other areas.

Because double track can't be straightened it is impossible to run a decent junction off it. In fact IIRC you can't lay a junction off it at all.

No track has a direction.
All track has direction. In fact every spline has direction.

You can lay it in any direction you feel the urge.
You can.

It is if you bothered to lay the track in the right direction. Personally I don't because imho it is easier to just rotate the signals. But if the track is laid as Martin suggests it is definitely quicker and easier to install signals.

And finally if finally why do you think Trainz provided direction markers if track is directional?
Track direction markers are an aid to controlling AI behaviour, they are utterly irrelevant to the 'track direction' being discussed here.

There's probably a moral here somewhere, but it eludes me...

TS12 doesn't come with a lot of extra built-in content - basically only what's required to support the new routes. As an after thought Auran's been putting the TS10 built-in content on the dls so you can down load it. Of course you really need a FCT if you have to grab more than just a coupe of small items.

If you like double track - well by all means use it. You heard a few of reasons why it's not liked or used by a number of people. But I think it does have its uses. I use it (actually bridge track but same asset class) for dualgauge track and while I use other methods of laying dg track using bridge track is (at least it used to be) a good way to do it.

But be advised in TS12 currently this type of track is broken. You can't insert spline points in it and you'll quickly find out that it does have a direction as it must be laid in 1 continuous direction. So 0--->0--->0 and 0<---0<---0 are ok but 0--->0<---0 and 0<---0--->0 are not.

These "bugs" may get fixed in a future patch but until then it must be used with the mentioned limitations. That is unless you like attached track splines forming circular paths or roller coaster track or zooming off to wherever bad behaving track splines go.
