. . . right here in the USA we have an example of how dining service can function well. . .
And methinks it
should function well when comparing relative costs with, say, the Empire Builder or Capitol Limited:
• Denali Star, 1 adult, Anchorage to Fairbanks, 11h45m, 355 miles, Gold Star Service. . . . . . . . . . . . $441 or $1.24 per mile or $37.53 per hour
• Empire Builder, 1 adult, Chicago to Seattle, 46h10m, 2205 miles, Roomette (high bucket). . . . . . . .$949 or $0.43 per mile or $20.56 per hour.
" " " " " " " " " (low bucket) . . . . . . . $443 or $0.20 per mile or $9.60 per hour
• Capitol Limited, 1 adult, Chicago to Washington D.C., 17h25m, 780 miles, Roomette (high bucket) $520 or $0.67 per mile or $29.64 per hour
" '' " " " " " " " (low bucket) $273 or $0.35 per mile or $15.56 per hour
The Denali Star is thus 3X higher on a per mile basis and 2X higher on a per hour basis when compared to the combined averages of those two LD trains in the lower 48. It is, however, impossible to assign a value to scenery.
