Dips in track

I do narrow gauge, but its normally flat, but it would be realistic if it was neither flat nor straight
 
Very little track in real life is either straight or flat.
And it gets less so between maintenance.

Well if you're just laying track on Trainz created tiles then you won't need to bother with the smooth button since Trainz creates flat smooth tiles. However if you're laying track on a DEM map then you'll have to use the smooth button, unless you're building a roller coaster.
I know that all of the track around here that I've seen UP & BNSF mainline is free of dips. However the local tracks which SJ uses to deliver cars around town is in pretty bad shape, loose road bed and ties which causes quite a bit of rocking and rolling but the SJ is limited to 25-30 MPH.

Yea Klinger if you're building narrow gauge then dips and such were very common as they didn't have the equipment then to produce a well compacted roadbed which allowed for dips. But narrow gauge didn't travel at the high speeds of todays trains either, I believe that there top speeds were around 40 mph, not 65-70 mph.

Actually, one of my (too many) projects is a DEM map of a line noted for the roughness of the ride. To preserve that I'm having to smooth the track by hand, one vertex at a time.
:hehe: It's a good thing I'm already going bald, or this would make my hair fall out.:hehe:
I love the smooth button.

That depends on where your track is. I was traveling on some high-speed trains a few years back and a glass of water filled to the rim didn't lose a drop on the ICE train I took in Germany. Even regular mainline was smooth and straight between curves. :)
 
This is how I think all track should be placed, nice and straight and no dips.

I found that in North America in general the quality of track laying is not so critical since ride pleasure is hardly a matter..
 
Oddly enough this sag in the mainline, just west of Alto Tower, beyond Slope Tower location

I presume that the railbed required too much fill, or leveling off than what the RR could justify to afford to spend.

But then again it might have been intentionaly graded this way, so as to give downhill potential runaways a level area to regain braking control, or vice versa uphill freights a good sanding level area to regain speed ?

Either way ... I have replicated the sag in Trainz.

EDIT: Excuse the poor quality picture ... My cheepo camera doesn't take very good long distance telephoto/zoom shots, and the area is largely inacessable, in a deep rocky cut.

Downhill freights usually stop there, being held at the signal, or are whining in full dynamics, with helpers holding back at @ 15 mph.

Uphill trains go run 8, to get a running start on the 0.41% grade prior to Alto Tower, to get up speed on the 1.0% incline, up to the sag.

Beyond the sag, the grade is nearing almost 2%

The area to the lower left, was the Slope Turntable, and the west end of the Slope Yard.

Slope Tower was on the lower right (long ago razed).
