Yard Ladder building

I'm a newbie when it comes to railroads but I assume by Yard Ladder people mean the set of diverging junctions that lead from mainline to various parallel sidings in a yard.

I've found a very simple and quick way to easily make good looking and symmetrical ladder. This will look very straight so it might not be exactly what you are looking for but it can be useful in other instances..

Let us assume we have one-track mainline and a 4 track yard. What you want to do is extend the yard tracks by a good deal, basically all of this extension will be removed completely on the furthermost (from the main line) track, and less of it as you get closer to mainline.

What you do then is you run a single track, at an angle, across all the sidings and the mainline, make sure the track doesn't actually connect to any of the existing tracks. Once you have finished this, use the straighten track tool on all existing track work.

At this point it gets silly. What you want to do is to connect your siding tracks with the crossing track (the one that runs at an angle) at the crossing points as if you were adding a single slip. Because this is not a slip, choose any radius as long as it looks fairly normal. Once this is added, make sure to straighten up any track that was bent by the addition of two turnouts, then repeat. When finished with all the sidings, delete any extruding track parts then make sure to check for bends that make it look bad. Remember to straighten track after each slip is made or else you will end up with a long s curved entry track.

I realize that this highly perfect and straight track is not exactly prototypical to many real railways but its common enough specially in tightly packed storage yards. Also this method is great for making big double-slip splits in middle of yard track, again it seems this is something not done in America but in Europe.

Step 1

Step2: Connect parallel track with the angled one:

Step 3: Straighten the bent track using Straighten Track tool (note the tracks are straight now, and the curve is smooth):

Step4: Delete excess track:

Step5: Repeat with other connections; notice that you get a second point switch, which we will need to remove later:

Step6: Remove any excess track, and the switch points that become red (no track diverging track connected):

Step 7: Finished product:

Templates ? Again, I don't know enough about Surveyor yet but I've spent a lot of time with it now, and figured some people might want to know this .. also this while templates are good, this can be used to create multiple, parallel entry tracks and/or connections to multiple sidings, some of which can be at different angle then other parts of the yard .. just my adding my few cents to the information thats posted here :) ... now to learn how to make actual curves :P

The proceedure is a good one particularly for places where the spacing and frog angles don't match available templates.

The mismatch of the cross ties (sleepers) shown in the above screenshot, that we all usually end up with when constructing spline turnouts, can with a little extra be made to line up as shown in the screen shot below. With 1 additional spline point in the straight leg you can adjust both spline lengths from the points to the frog so they match up pretty closely - if the track direction is the same. I usually make turnouts with a spline point in each leg at the point of the frog. Then adjust the length of the curved leg to match up. You may not want to make all like this but in places where you want them to look good it's worth the effort.

Speaking of track direction, while many on the forum swear that track direction is important to get the AI and signals to work apparently the peope who wrote Suveyor didn't consider it necessary. Inserting spline points and junctions doesn't always preserve the track direction and you may have to go back and relay a section or 2.

I just tried it, that's a great idea.

Is there a template for making even spaced parallel tracks?

Check my site for a collection of surveyor toolz, there are a couple of items there that would help.
Do a DLS search for martinvk, he has made a few parallel track tools. :)

Never thought of that, thanks Bob!
 
Templates tend to be more restrictive than creating tangents, which can be created at any angle, for any turnout or curve... With the use of only templates for parrallel track, and a bit creative thought going to where else you can put tangents, you can come with all sorts of creations.... The ones shown are actually all accurate to plans.




Note: To get really accurate curves, it is best to use the trainz ruler to measure where to put the spline points on tracks. Place one end of it where the straight tangent tracks cross, and the other a set distance along one track. Add a spline point there, and move the end of the ruler along the other track until it measures that distance where you add the second spline point. I have tried to demonstrate this in a video too:

No, don't relay the sections to reinstate the direction, it's not necessary. Just add another spline point and then delete it. This will reverse the direction and what is more, this works on all splines.

If houses are back to front, your fence the wrong way round, or your track running in the wrong direction. Add a spline point and then delete it.
