Kato curved double viaduct track ??

[domino]

I just realized that there are 2 types of curved viaduct double track from Kato(silly me) , the 20-541 and the 20-544, is the only different that the 20-544 make a bigger curve, or does it  ??

20-544 is a super-elevated viaduct curve.  Super-elevated curves need transition pieces. It is also r414/381.

20-541 would be curved viaduct flat track.

The 20-541 was discontinued several years ago after the banked version was introduced. It doesn't even appear on their stock list anymore (discontinued items remain there for some time).  You might still find some in a store, but it's pretty rare.

So there is no difference between the 2 tracks , other than pre-cast concrete and super elevated ?? I have never seen a 20-544 so i have not seen the difference close up.

 

With the 20-541 it takes 4 pcs to make half a circle , but with the 20-544 it take 3 pcs and 2 pcs 20-545 to make half a circle , is this correct ??

 

I dont see the advantage is this ??

It allows you to have trains tilted 4% like the prototype.

I see, but the 20-541 have a tilt also ?

 

Im not trying to difficult, only to understand the difference and the advantage with the 20-544.

When it doesn't say super elevated than its just regular level track.

 

You want the super elevated; it's canted.

 

Check out Richard Hammond's Engineering Connections - (S03E06) Bullet Train on the BBC: http://youtu.be/OXdReBMowfQ

 

Talks about all aspects of bullet trains and tracks. Complete with 1/5 scale model earthquake simulator (having a bubble with it). So interesting that I'm watching it again.

 

Leaning into the turns is something Homer discovered a long time ago.

I use Kato V11, and V16 tracks. Both create that tilt effect to high speed passenger trains. The V16 is an excellent track for Acela Express. No more derailing, or uncoupling.

Does you Acela like the inside curve  of the V16 as well? I ask because I believe it is under Bachmann's recommended minimum of 19 inches.

No problem with inside curve of the V16.

My father's Acela set runs just fine on the outside curve of the V16, but does slow down a little on the inside.  It hasn't derailed or anything like that, but you can tell the cars are being bent as far as they can go.  The best I can describe it is that it slightly "drags" through the curve on the inside track.

 

I still maintain that the Acela is a very cool set and Bachmann did a great job with the detailing.  If it were not for poor couplers and the need for a 19" radius, I think this would have been a best seller for Bachmann.
