- This differs here in Canada slightly. Rule 10(b) states, "Where the use
- of torpedoes is required, a duplicate torpedo must be placed on the opposite
- rail to explode simultaneously." It is possible up here, that only one
- noise could be heard. Besides, in both cases the duplication is generally
- a precaution against the possibility on one not working.

- The CROR requires a train, if not already moving at restricting speed
- (able to stop within 1/2 sight distance, but not greater than 15 mph)
- must slow down to this speed within 3000 yards of the sound of the
- torpedoes. Some circumstances reduce this to 2000 yards.

- How complicated life can be for the crew of an international train. :-)
