Joel, in the steam era Tidewater Associated Oil Co. had three branches,
eastern, midwestern, and western, each with their own tank car fleets.
Eastern tidewater cars operated under TWOX reporting marks, midwestern
under TIDX reporting marks, and western (Associated) under AOX
reporting marks. TWOX cars were common in the northeast. As others
have pointed out, P2K accurately modeled AC&F 10K gal. Type 21s that
were rostered as TWOX 1017-1468, which would include TWOX 1439. TWOX
1839 isn't listed in the 1/53 ORER; TWOX 2050 was an 8K gal. car in the
2001-2095 series for which there are currently no HO scale models.
