Thank you very much for being here today. What you had to share with us was very interesting.
I just want to ask a question because we've had previous witnesses in previous sessions, obviously. In hearing from the Teamsters and the workers of the railways, they said that often, one, they did not know what was in the cars; and two, if an accident happened, they would not know how to respond, that the training was virtually non-existent, etc.
Could you clarify that for me? That was something you talked about today. Is there training for the workers? How do they know what's in the cars?
I want very short answers because I have a number of other questions.
