The South African Railways Class 6E 4-6-0 of 1898 was a steam locomotive from the pre-Union era in the Orange Free State.

In 1898, the Oranje-Vrijstaat Gouwerment-Spoorwegen ordered its final six new Cape 6th Class locomotives. When British forces invaded the Orange Free State during the Second Boer War, these locomotives were taken over by the Imperial Military Railways. After the war, they were renumbered into the Central South African Railways roster. In 1912, when they were assimilated into the South African Railways, they were renumbered and designated Class 6E.

The original 6th Class 4-6-0 passenger steam locomotive was designed at the Salt River works of the Cape Government Railways (CGR) at the same time as the 7th Class, both according to the specifications of Michael Stephens, then the Chief Locomotive Superintendent of the CGR, and under the supervision of H.M. Beatty, then the Locomotive Superintendent of the Cape Western System.

The first ten 6th Class L locomotives of the Oranje-Vrijstaat Gouwerment-Spoorwegen (OVGS) were purchased second-hand from the CGR. These were followed by orders for 24 new 6th Class L2 locomotives, directly from the manufacturers, which were delivered between 1895 and 1898.

A final order for six more locomotives was placed with Sharp, Stewart and Company in 1898. Three of these engines, designated 6th Class L3, had been delivered and numbered in the range from 96 to 98 on the OVGS roster, when British forces invaded the Orange Free State during the Second Boer War and the OVGS was taken over by the Imperial Military Railways (IMR). When the other three locomotives arrived, they were therefore numbered in the range from 370 to 372 on the IMR roster.

These six locomotives were delivered with larger cabs than their predecessors and with Type XC1 bogie-wheeled tenders. The first three engines retained their OVGS numbers until the war ended in 1902, when they were renumbered onto the Central South African Railways (CSAR) roster. The other three locomotives retained their IMR running numbers on the CSAR and all six were designated CSAR Class 6-L3.
