Because then you run the risk of linebacker11 and flambeau teaming up and laying on the train line in a horizontal protest position, demanding to see into the oil carriages since they are convinced the carriages are in fact filled with rum and on it's way to Melbana's Christmas party evidenced by AP not releasing a statement indicating the exact volume filled of each carriage.

Also when someone asks at what hour does the train leave for the depot at the previous webinar, AP would reply he does not have that information at hand but said it would be in the next 24 hours. This would cause flam4beau to completely lose his marbles and contact the IAEA since AP did not stipulate there are no nuclear materials on board, meanwhile linebacker frantically taps away on HC ".....so at the train line.......whereis the oil....[I dont see any]....MAY...@$#@#$.....$#@43.4.*...these tanks are empty.....[train speed?]...$%%^%....3$@4..#43..

A barge could potentially be worse, since they would most likely rummage up Greta or someone with a boat to block the canal Ever Given style, chanting and shouting from the bow that AP did not specify the exact quantity of oil on board thus we could potentially have an ecological disaster if the oil is not viscous enough. International press would swoop on this story due to Greta's involvement, and linebacker would now have an even bigger international audience chanting and shouting, "where are the shut in pressures!" whlle flambeau holds up placards of HC screen shots to the press helicopters showing the deception in Errol's answers indicating that this barge, is in fact, filled with peanut M&Ms.

So an oil pipeline is much safer for everyone.
