1851 'It will be remembered that the first turf was turned at Bombay, on the 31st of October, 1850. Very little was done for the first eight months, till Messrs. Faviell and Fowler, the contractors, at one end, and Mr. Jackson at the other, took matters in hand. The work appears to have been one of great labour and difficulty. In addition to a most trying climate (in which the constitution of Mr. Fowler, the partner of Mr. Faviell, well as that of many of the English labourers they took out with them, failed, Mr. Faviell found himself, in March, 1852, working single-handed, his partner having gone to England for the benefit of his health.

1866 Accident. '...a frightful accident on the Great Indian Peninsula Railway, at the reversing station of the Thull Ghaut, which resulted in the instant death of six or seven persons, and the serious injury of another. Just before coming to the scene of the accident there is a declivity varying from 1 in 100 to 1 in 37. All that is known of the circumstances is that the train, as it came down the gradient, obtained tremendous velocity, rushed past the station so rapidly that nothing but its momentary whirl was heard, dashed through a barrier at the end of the rails, and literally leaped down the precipice beyond. One of the guards jumped off and was terribly injured; but the other poor fellows who were in charge stuck to their posts and were killed in the crash. Scanlan, the guard who jumped off, is not considered to be in immediate danger, but his jaw being broken, he is unable to speak.'
