As traffic on the line increased, a second platform opened at Alberton in 1878 and the single track was duplicated throughout in 1881.

Goods sidings were installed in 1892, controlled by a signal cabin adjacent to the Fussell Place level crossing.

As traffic declined in the second half of the 20th century, the goods siding and signal cabin were taken out of use in 1953.

Alberton station has been unattended since 1 September 1987, but the building on the first platform is now used as a hairdresser.
