Good afternoon.
Burlington's Denver Zephyr was considered the flagship of the railroad. It was a very popular train for many years. It was a daily overnight train between Chicago and Denver. Its schedule for the 1,000 mile trip was 14 hours, and that included several stops at stations along the way. E-units were the normal power. Below is an 18-car DZ with 4 E-units in the summer in the 1950's.
The Burlington Northern merger was March 2, 1970. BN continued operating the DZ until Amtrak was created on May 1, 1971.
Winters could be very challenging to the DZ because heavy snow with drifting could affect tracks on the DZ's route. CB&Q had a large rotary snow plow stationed in Lincoln, Nebraska, and it had smaller plows located along the route.
A major blizzard in 1971 was one of the greatest challenges to operations of the Denver Zephyr. An SD7 and a GP9 were added to the normal E-units to help the train power its way through the heavy snow. Even with plows working ahead of the train, it was 12 hours late stopping in Lincoln. The schedule was to arrive in Lincoln at midnight CST, 7 hours after departing from Denver. The train arrived in Lincoln at noon. Crews at the station thawed out the steam pipes for heating the train before it continued its eastbound trip. It took another 12 hours to get to Chicago.
The schedule 14-hour trip from Denver to Chicago took 29 hours.
Below is a photo of the train in Lincoln.
When the railroad companies operated trains before Amtrak, they did all they could to operate regardless of weather. Today's Amtrak wimps out for bad weather and cancels trains.
