The Coachman:

Just about got enough embers left for one more run to the docks. I should think we'll be scraping along a bit towards the end, but I can refuel at the coal bunker in Chandlers' Alley. Ah - three passengers headed to the coast, along they come. Two silver coins, and a bronze penny for the bird (livestock rates; that'll be an extra penny every time it soils the interior).
