MF Track Question

^lol.

The 2-rail track on Intamins is just for areas of minimal stress, i.e. brake runs, launches, loading/unloading platforms.

Or... is it?

Good point, but I thought we were talking about MF.

No you didn't.

Huh?

Ive always thought that the more rails, the less support needed.

IE.. 2 railed section has more support then a 4 railed section..

..for example.

I dunno, X at SFMM has 4 rails and its supports seem fairly close together in some spots.

Of course, X's trains probably weigh 3 to 4 times as much as Intamins. Superman: Ride of Steel at Darien Lake only uses the triangle track

or the two-rail track. Perhaps Intamin didn't develop the box track until 2000. Nonetheless, I agree that with less support along the track spine, more supports are needed to withstand the loads from the roller coaster.

X isn't Intamin now is it?

Yes. X went back in time and requested that Intamin design it instead of Arrow Dynamics.

wow.

Haha, nice try. lol

Yeah, X didn't like what Arrow did to it or what it did to Arrow. Nice. lol

I think 4 rail is stronger when it comes to weight distribution (aka long areas of unsupported low stress areas)

Then 3 rail is for areas of high stress distribution.

2 rail just sucks and can't do anything without 10,000 supports per foot.

My 2 cents

Nice mature response at the end with the 2 rail. 2 rail has a reason. Train is going 5 mph into the station, I don't think you need to waste money on 3 or 4 rail.
