This series contains records of the Railway Commission (1873-1888) and of its successor, the Railway and Canal Commission (1888-1949). The records consist of registers containing summary particulars of applications to the commissioners and of registrar's minutes, 1934 to 1949. On occasions more than one register may need to be consulted because there are some overlapping dates. This is due to entries under some of the alphabetical sections of the register filling up sooner than others, and being carried over to the next volume. The series also includes some seals, ink stamps and obsolete file covers. There is also a selection of case files containing a variety of documents, such as applications to the commissioners, accompanying maps and plans and subsequent orders, and appeals against rating valuations.
