The Tocumwal Rail Bridge is not on the Narrandera-Tocumwal railway line (i.e. Tocumwal railway line, New South Wales), it is on the Seymour-Tocumwal railway line (i.e. Tocumwal railway line, Victoria). Tocumwal is a break of gauge station. It is the Victorian Railways broad gauge line that crosses the river to meet the station, the NSWGR standard gauge line stops at the station and does not cross the river. Please correct. -- Mattinbgn (talk) 06:03, 16 June 2018 (UTC)Reply

Apparently the New South Wales Government is confused about its own railways. Thanks for the heads up. The Drover's Wife (talk) 07:56, 16 June 2018 (UTC)Reply

Cast iron versus Wrought iron

edit

Assuming that this bridge was made too early to use mild steel, it would be made out of wrought iron. Although there might be a little cast iron used in specific places where it is not in tension or shear, the structural members are too long to be made out of (brittle) cast iron.
