The lower deck will now become the baggage compartment. Not much additional weight is added to the trains consist in this configuration. In addition a sleeper car passenger with checked luggage might gain managed access to a checked luggage if so needed. This service would not be available to the coach passenger holding section. The all equal in height cars will command this.
Fuel costs a lot of money.
We may want to upgrade this site. We hade a transformer problem up on the arrival, therefore we did arrive late. This was not an Amtrak condition. The departing was much delayed because of the express freight car hook-up. Tow hours in all.
