Side-by-Side Tunnels

[Jedimarine 119]

Just curious...I was hoping the new nam might provide it, but alas...

Is there a method like the 3k "crossover" trick.

my driving interest here is in side by side rail tunnels.

I've got some booming rail depots in the heart of a residential area...but to expand the area further I need to get the rails underground.

but to get the 4 tracks out of the depot and into tunnels requires a minimum of 4x7 to spread them, lower them and get them into tunnels

This is unacceptable consumption of space  for the advantage of putting them in tunnels.

Is there any way to get the 4 tracks to run side by side down and into tunnels?  2x4 would be ideal...3x4 I could make work (I'd lose the first cross street....or more likely set in back a block and eat into a zone.)

I tried to search the omni but wasn't immediately successful (the lag on here today is making page flipping atrocious)

If anyone knows a method or can point me in the right direction, I'd appreciate it.

peace!

I too was wondering if theres a way to do this. It stinks to have two tracks in a viaduct and

then when I try to get them to run under my city instead of cutting through it I have to merge

the second track into the first. It looks kind of stupid..

Hello Jedimarine,

What is the problem - with proper slope and minimum-length - I've been able to tunnel side-by-side for nearly forever (at least since SimCity4 was first released).  I've placed Monorail Tunnels - then put avenue tunnels on one side - and ground rail tunnels on the other side; the trick here is to place the tallest tunnel first - then the next tallest - etc.

Then again - I'm not a puzzle piece user - I drag my transit networks.

Although - if the Maximum Tunnel Height is too low and/or the Minimum Slope to Start A Tunnel is too high - then maybe you may want to rewrite one of these rules.

Okay...can you run me through that again...I see the image of 4 rail tracks side by side, but you were talking about monorail tunnels and avenue tunnels...do I build those and then bulldoze them?

Can you give me a step by step to how you got to the image there?

Hello, again, Jedimarine,

You don't have to put a monorail (or avenue) tunnel in - unless you just want to.

That picture was a quick dirty job -

In God Mode:

- I raised the terrain (on one tile - all four sides) by five easy steps/clicks,

- I used the level brush to raise an area of 4x3 tiles to the same five-easy step height,

then In Mayor Mode:

- I selected the ground rail tool,

- drug the first tunnel across three raised tiles (and two slope-ing tiles),

- repeated for second, third and fourth tunnels - each one tile over from the previous.

So, in summary - what is needed is a high enough slope (for ground rail - five easy god mode steps/clicks) for the tunnel entrance, the exit should also be sloped - but doesn't have to be as high as the entrance; and the tunnel has to have as a minimum:

1) a sloping entrance tile (for each tunnel - on side by sides, try to make these the same),

2) at least three tiles that are over the tunnel height (again for each tunnel - preferably build tunnel before developing end tiles),

3) an exit tile (for each tunnel - again, on side by sides, try to make these the same),

or a total of 5 tunnel tiles - plus, of course, one above ground tile at each end of the tunnel.

If you have to dig - to get the slope for either the exit or entrance - allow two less slope-ing tiles to get your rails down-to or up-from your tunnel's entrance/exit. And having developed tiles at the top of your entrance/exit slopes doesn't help; these may be developed after the tunnel is placed - but may need to go away while the tunnel is being placed or re-placed.

Side Note - depending on orientation (i.e. dragging from east-to-west maybe-okay, but dragging west-to-east maybe-not-okay) - the game may or may not allow the above ground tile next to the tunnel entrance/exit to be on a lesser (and opposing) slope.
