Kalamazoo, followed freight train to Michigan City yard and stopped at signal near Center Street. Got proceed signal from some one on ground, pulled up to Michigan City, stopped at standpipe and took water. While following this freight train, we stopped first between Dowagiac and Pokagon on account signal at danger. Stopped again at Pokagon and Niles for same reason, this freight train being ahead. Leaving Michigan City, had clear track to East Gary and there caught block of train ahead, reduced speed, but did not have to stop, as block cleared before I reached it. Reduced speed going through Gary to comply with rules, and saw no more signals at caution or danger until approaching curve east of Ivanhoe, where I found second signal east of wreck at caution. Was going about 25 miles per hour at this point, but did not reduce speed, as I expected that the next signal would probably clear before I got to it, or that I would see it, if at danger, in time to stop. The wind was blowing very hard into cab on my side and I closed the window, which made the inside of cab more comfortable. Before reaching the next signal I dozed on account of heat in cab and missed it. Not realizing what had happened to me until within 75 to 90 feet, I awoke suddenly and saw the tail or marker lights showing red on a train directly ahead of me. Not realizing that the rear end of this train was so close. I started to make a service application, but before completing it placed brake-valve handle into emergency position. We struck almost instantly after making the brake application. Don't know whether I closed the throttle or not, but think I did. Looked to see where the fireman was and saw he was running toward the gangway. Did not see a fusee, hear a torpedo, or see any other warning signal up to the time I saw the red tail lights. Wreck happened at about 4.05 a.m., June 22, and I stayed there for an hour or more assisting in getting people out of the wreckage. I have been in the service of the Michigan Central Railroad Co. for approximately 28 or 29 years, the last 16 of which I have been continuously employed as an engineer. I am in perfect physical condition, as well as
