If the weather is unfavorable ANYWHERE on your route, you face the real potential for either departure or arrival delays at any of the airports you originate from, land at or take off from during the flight.…or if the weather was unfavorable anywhere along the route that your plane took to get to your airport. Unfortunately airlines schedule planes too tightly, so that any schedule problems ripple through the whole commercial aviation infrastructure the whole day before there is a single catch-up opportunity. |

The bottom line is that a combination of the bad economics of air travel coupled with the need for security and the weather sensitive nature of aviation makes air travel in much of the US degrading and impractical, especially when faced with fair competition. |

Think more laterally: Assuming the money were there to allow an underground HSL through Birmingham, how would that change the equation?After all, that was the engineering solution to bring Eurostar to St Pancras! |

That would, of course, work. |

'...an underground HSL through Birmingham...After all, that was the engineering solution to bring Eurostar to St Pancras!' And although tunnel boring machines are always expensive beasts, costs (such as diverting existing underground utility services, etc.) can be minimized by tunnelling below existing surface rail RoWs, which is what was done for much of the route into St Pancras, which lies below (successively, east to west) the Tilbury loop, the Barking-Gospel Oak line and the North London Line. |
