This was a Texas oil-patch railway that covered about 25 miles of mostly flat land on 60-lb rail. It connected Dayton, which lay on the Texas & New Orleans Railroad (subsidiary of the Southern Pacific), to Humble Oil's Baytown refinery. The D-GC's earnings made it a profitable line; passenger earnings ($5,000) were dwarfed, as might be expected, by the $157,000 of freight revenue.
Apparently needing a good local-service locomotive of moderate power, the D-GC Rwy and the builder settled on the 4-4-0 layout and produced one of the last such engines (works #55150) supplied by a US builder to a US railroad. It had 8" piston valves, but was superheated to a useful degree. Along the boiler were arrayed three domes, the one forward for sand, the one in the middle for steam, the one just behind that for more sand.
The D-GC was sold to the Southern Pacific in 1926, which leased the line to the T & NO for 8 years, then merged all of the SP properties into the T & NO. The D-GC's 104 was renumbered 192 on the SP, then 223 on the T & NO.
