Allan Peden has a great story here about his involvement in a wreck at Carman Junction in western Winnipeg in the early morning of October 17, 1956. CN Extra 2503 East ran a red board at the Junction and collided with a train coming off the Carman subdivision. Mr. Peden was the head-end brakeman in the engine. The fireman was critically injured when jumping from the engine, and died later.
The Carman subdivision was sold to the Central Manitoba Railway, but Carman Junction still exists and is used. These days they have signal lights instead of boards!
