not a single tunnel. It actually consists of three parallel tunnels: two 7.6-m diameter rail tunnels and a 4.8-m diameter service tunnel. Single-track rail lines are laid down in each of the running tunnels

flange joints to the straight run of tubing, are used. The steel tubes range from 1 to 2 in. in diameter. The ratio of boiler to economizer heating surface is about 2 to 1. 3. Economizers are parallel

extremely weak: for a cylinder a metre long the amount of surface disturbance would be a fraction of the diameter of an atomic nucleus. For 40 years no one seriously looked for gravitational waves, but in the

circuit may be very damaging if a large amount of current is involved. 4. Frequently, if small diameter wires are heavily overloaded, the wire catches fire. In order to prevent overloading of a circuit
