Q. You were a conductor on trains that ran double-headers?
A. Yes.
Q. How long have you been running on trains that run in that way?
A. I cannot tell the length of time precisely, but I was running them from the time they started—that is, from the time they started to run through freight as double.
Q. About how long?
A. I cannot tell.
Q. Two or three years?
A. I hardly fancy it could be that long. I should say a year.
Q. Were you at the depot or about the depot on the morning of the 19th—Thursday morning?
