Worried that a short circuit on an electrical outlet could bring down the rail network? System doesn't seem very fault tolerant. This is like a kid with a .22 rifle sinking a battleship!

Stability during burn
Any difficulty in obtaining simultaneous ignition and thrust buildup on the multiple rockets would exacerbate stability problems of keeping it on course during the boost phase. See the "typical" curves given for one brand of model rocket engine (http://www.hobbylinc.com/rockets/info/rockets_enginefacts.htm) . No production tolerances are given.
