Actually, it was also Mr. Holliday who referred to a culture within CN that was not conducive to allowing SMS to be implemented properly. I believe Mr. Holliday himself had worked for a number of different railways over the years.
In fact, Mr. Rhodes had worked for BC Rail before it was taken over by CP. There's a guy with a fair bit of experience who talked about the days when he worked for BC Rail where there was accountability, where the opinions and the concerns of employees were taken at face value and were acted upon. Suddenly there's a new culture imposed upon them by CN that is poisonous, that is working actually counterproductively to what we had hoped would happen under SMS.
