Re: On the advisability of the use of sentient trains

Sir Hatt,

The board of directors would first like to commend you on the overall excellence of the Sodor Railroad’s operations. Under your leadership, new branch lines have been opened, unsafe lines repaired, and freight shipments have increased 20 percent year over year for the past five years. Bravo, Sir.

It is unfortunate, therefore, that we must once again question your decision to employ sentient railway engines and cars in lieu of the more typical non-sentient trains found on most railroads. These self-aware trains, especially the engines, have produced continued disruptions only outweighed by your hands-on management style, and forceful manner in dealing with them.

As the father of a 3-year old this is very amusing. Follow the link, there is more.
