The elder Brunel was habitually absent in society, but no man was more remarkable for presence of mind in an emergency. Numerous instances are recorded of this latter quality, but none more striking than that of his adventure in the act of inspecting the Birmingham Railway. Suddenly in a confined part of the road a train was seen approaching from either end of the line, and at a speed which it was difficult to calculate. The spectators were horrified; there was not an instant to be lost; but an instant sufficed to the experienced engineer to determine the safest course under the circumstances. Without attempting to cross the road, which would have been almost certain destruction, he at once took his position exactly midway between the up and down lines, and drawing the skirts of his coat close around him, allowed the two trains to sweep past him; when to the great relief of those who witnessed the exciting scene, he was found untouched upon the road. Without the engineer’s experience which enabled him to form so rapid a decision, there can be no doubt that he must have perished.
