The train would have derailed its self


Unfortunately I work on the railway so couldn't help notice that building a CWR railway in the desert would only have one result, the first train would result in a massive buckle and the train would derail! These vampires should have payed more attention to metallurgical properties of steel, teach them to have no eyes.

Okay, I'll bite: what is a CWR railway, and why would it buckle in the desert but a normal railway wouldn't? I tried to look it up, but none of the possible explanations made sense in this context.

Continuous Welded Rail. Sections of track are welded together instead of butted together and spiked to a cross-tie. Since continuous and sectioned track each use cross-ties and/or rock beds, I can't see why the OP claims a desert CWR track would buckle and toss the train. Perhaps he'll post and explain.

Perhaps, he infers that in the desert, the Continuous Welded rail would NOT have enough room to expand and contract, due to the inherent HIGH temperatures during the day and freezing temperatures at night. I know that in some iron structures, like old bridges, they butted beams together and riveted them, rather than welding them together to give them more flexibility, taking into account the shift due to temperature changes.

That's just my own wild guess, but I too am interested in the O.P's response :D

That's a good hypothesis. I wish I'd thought of it.

This film has a Sci-Fi element, hence it could be a high-performance alloy that is design to withstand the expansions and contractions of hot days and cold nights.

A superalloy, or high-performance alloy, is an alloy that exhibits several key characteristics: excellent mechanical strength, resistance to thermal creep deformation, good surface stability and resistance to corrosion or oxidation. The crystal structure is typically face-centered cubic austenitic. Examples of such alloys are Hastelloy, Inconel, Waspaloy, Rene alloys, Haynes alloys, Incoloy, MP98T, TMS alloys, and CMSX single crystal alloys.


And why blame the vampires if the humans constructed and used it? And obviously they used it for a longer time without any major problems.

Continuous weld rail is laid under tension so that when heated the effect of expansion is to relax that tension. But there are limits to the technique which the OP might have in mind: too much heat, too much expansion and the rails will buckle in the end.

A desert implies a lot of heat (yes, I know there are cold deserts, but this one looks hot) so not a good place for CWR.

Honestly though, not something I'd noticed and not an issue that in any way effects my enjoyment of the film.

Man... THIS just ruined the movie for me.
