Re: Re: The destruction of St. Stephen’s Green
Thats fucking scandalous. This is going to be a disaster.
Why twin bore? All the metros I’ve used have all been single bore. It’s not like the luas style trains are going to be too big to fit in the one tunnel?
Single bore metro tunnels are typically in use on older systems. They do not conform to modern safety standards. If a train travelling in one direction experiences a problem eg fire or derailment, it would be disasterous for both that train and one travelling in the opposite direction. The double bore system reduces that risk
