Over the years I have had to replace track due to poor installation that resulted in kinks and dips, uneven curves and humps. None obvious to the eye unless you looked for them or used a level.

How do these trains not just fall of the rails?

Careful planning, and knowing the tolerance of equipment to run over faulty track at certain speeds is contributing to his/her success in that video. On the other hand, it does not show how many takes and failed attempts it took to produce said video.

Properly weighted equipment, running at slow speeds, with carefully planned "faults" can be a successful way to model degraded track.

The sharp radii from the turnout, dips in the rail and zig zags are obvious in your video.  They look like something from the World's Worst Railroad Track videos on Youtube.

The Rochelle diamonds, just before they were rebuilt, gave similar sickening lurches of the railcars.  Other than that, bobbing and weaving is not usually seen on Class 1 railroads to that degree, or if it is, I just haven't seen it.

Don't know why they don't derail.  I wouldn't have the guts to post that video if it were my layout.

Didn’t think about how many takes it might have taken to get the video. I jus could not believe anything would negotiate those curves, dips, kinks and humps without derailing.  Even the through freight going much faster than the switcher seamed to go right through.

Maybe it’s all photoshop or something like that.  I thought there nay be some antiderail secret that would counteract bad track like a KA fixes conduction problems. HA Big Smile

I do believe the guy that made that track is on this board.  I do remember reading and seeing those clips when he first did it then explaining how he built the track     As he stated here,  he has no issues with it

 If you've seen some of those videos of real railroads with poor track, you can see they can take a lot, and still not derail - most of the time. Models, unless they also have fine scale wheels, have much greater tolerances (percentage wise anyway, of course) because the flanges are relatively oversized and so are the wheel tread widths.  Plus some careful construction - tighten up BOTH truck screws on one of those cars and watch it instantly derail on those humps. 

 It's not going to be derailment free - much like the protoype, it will work fine - MOST of the time. Once I had the idea of taking some old fiber tie flext track and making the tightest, curviest bit to add on to my trolley line through town. I curved the track as tight as I could - in one spot there actually was a slight kink in it where I overdid it. Yet the 4 wheel trolleys would run through just fine - 99% of the time. I don't have any pictured of that long ago layout, but the curves had to be 4" radius or less. If I cranked up the throttle though - they would derail 99% of the time. Slower speeds, just fine. Same with this layout - doubt anything will negotiate that track at warp speed. If you watch some of the closer shots you can see how the trucks tilt and swivel to handle the dips - that's the key.

Other than that, bobbing and weaving is not usually seen on Class 1 railroads to that degree, or if it is, I just haven't seen it.

And that's way you are required to read the daily bulletin for any restricted speed track because track isn't always perfect.

Simply put  being lead by all those self proclaimed hobby "experts"  can be misleading..

One  can fully understand how forgiving our  models are if we can control the wrist that turns the speed knob and less then pefect track works just fine as the video shows..

AS far as your question is concerned, there are several responses addressing it.  But, what struck me was the great weathering on the locomotives and rolling stock.

Geez, Mike, now you got me wondering. But that track work is so bad, it must be my layout. No?   Confused

[edit]never mind.  I thought it was n scale at first.[/edit]

Run for 1 hour at full speed in each direction with a load of good quality cars.  If it doesn't derail you're in good shape.

If it derails, see if you can correct the track in place.  If not, yank it up and repeat.  I did that 4 times so far on my son's mini layout.

I can see a couple of things that might be keeping the wheels on the track.

One is that the diesels are all two axle trucks. If they had three axle trucks they might not be so forgiving.

The second is that the track has low points on it but it doesn't seem to have any short high spots.

The derailment issues that our club has experienced on our portable layout occurred where the track was pushed slightly upward at the rail joints, and they always occurred with three axle trucks.

Did the video say this was N scale?

.

It looks like HO to me.

.

My N scale layout with code 80 rail and pizza cutter wheels never derailed. Some of our track was as rough as this.

If you watch the video, right at the beginning it says it's HO scale.  Shortly after, it says some of the track is hand layed with N scale track, and wood ties.

yes but you would think that would make derails happen easier.

REALLY? N-SCALE is more forgiving than HO?  I never would have thought that.

Both scales is about equal in the forgiving department however,C80 track and pizza cutter (deep flange) wheels is most forgiving in  N.

In HO you can use two Peco switches and 4 pieces of flex track and have a switching layout on any smooth surface without the need to fasten the track in place..The same can be done in N.

That is really nice modeling.  I've seen a lot of crappy track in real life and it's interesting to see somebody model it successfully.

On the other hand, it would look a LOT better if he cut his train speed in half and slowed down his starts and stops.
