Bret is right about the surreal feeling running at night, at least at first. I have not had an opportunity to ride the train at night but I have fired a few night runs in the #19. But as a relatively new oil fireman the feeling dissipates quickly when you realise you cannot see the color of your smoke. Many railroads installed a stack light for that reason but the 19 is not so equiped. If you care about doing it right, and not all of our volunteers do, you must closely watch your fire in the daylight and learn to judge the look of your fire rather than the color of your smoke. Coal and wood firemen already do this, but for oil firing it ads another dimension to doing a good job.
