| Comment | Was costed at roughly £2.2 billion around 2007ish for a second subway loop. Likely double that and you're close to the cost today.
For that money, as Mr Yermawshole says, you build an entire light rail network and even a couple of interchange hubs with existing rail and subway stations. Definitely more bang for your buck that way, plus it can be built incrementally.
One of the many benefits of a light rail network is you build it piece by piece, and that each piece can serve places that might otherwise be awkward or hard to justify serving with an out-and-out subway line / circle. You've simply got more flexibility with where you place the lines.
Places like Castlemilk for example, which I think is included in the Metro plans, but would likely be left behind by a subway loop for the east end. |
