The NRL 4-4-0Ts were built around the 1830s or around it at NLR's own workshop, later rebuilt with a covered cab. These engines were meant for interurban trains. I couldn't find a lot of info on this type of engine so some stuff said here may be incorrect.
Engines made by me NLR Some engine parts made by steamship999_alt (plz dont send an intergalactic ballistic thravel) C2a
