In January 1886, the contract was signed with that company that would take over the construction of the railway line. Immediately thereafter, the builders, Lewis Jones and Thomas Davies began with the construction.

So the name of the village was Trelew ( Tre = village and the name Lew Lewis) in honor of that citizen, who drove the development of the colony forward.
