I tried to skim through the posts here w/o spoiling the rest of the episode for myself, so I apologize if this has already been discussed.
I'm caught up in something dealing with the Methylamine which looks like its going to be a huge plot point.
They said they were taking 4% of the Methylamine from the railroad tanker. Assuming 1,000 gallons was 4%, that would mean the railroad tanker would have been carrying 25,000 gallons of Methylamine. The interwebz tell me this part is completely feasible (first answer I found about avg. train car liquid capacity was between 16k and 30k gallons).
What I'm totally miffed about is the fact that Jessee & Mike found a (local) buyer in a matter of a day to sell their respective 333.33 gallon shares of the Methylamine at $5,000,000 a piece.
At that rate, the single railroad tanker (which was placed in the middle of a train operated by 2 younger/gruff-engineer guys with no type of security on board or surveillance system, despite the known 'black spots' on the route) was carrying a payload with a
(illegal) street-value of at least $375,000,000.00. Maybe I'm just ignorant, but that is totally unrealistic, right?
Even more mind-boggling is the fact that the Methylamine seems to be +95% of the production costs and troubles of Walt's Meth, and Walt has already calculated that the 1,000 gallon heist would result in $300,000,000 of revenue. If that's the case... If somebody could obtain a single railroad tanker of Methylamine, they would have the ability to produce ~$7.5 BILLION worth of Meth with minimal costs for the other materials needed.
With one train car of that stuff, you would have the means necessary to generate more than the GDP of 65 different countries in 2012. Can somebody else chime in and hopefully tell me I'm not crazy to think that its completely insane to think that a product with that much (illegal) value would be transported in the way the show has depicted?
