History

A total of 20 Ec class engines were built by Baldwin Locomotive Works, Philadelphia, in the first half of 1901, and entered service with the WAGR later that year.[2][3] The following year, Baldwin built the first of two batches of the C class, a lighter version of the Ec class.[4]

Initially, the Ec class' main task was to haul heavy trains on the Eastern Goldfields Railway. Between 1920 and 1923, nine Ec class engines were lightened for use on the lightly laid Northam to Mullewa line, and reclassified as the Eca class.[3][5]

All 20 were withdrawn between 1923 and 1925, with the frames, wheels, cabs and tenders married with new boilers, cylinders and valve gear at Midland Railway Workshops to become the L class. The costs of the rebuilds were recovered within four years through lower maintenance costs.[3][5]

By the early 1930s, frame cracks were beginning to appear with 14 receiving new frames. They were replaced in the 1950s by the W class.[3][5][6][7]

gollark: Yes, this was a question on some maths homework I did ages ago. Consider: n time units after you start doing this, if your money increases by a factor of a per time unit (1 + interest rate % / 100) and pay in b per time unit, you will have
gollark: I'm sure you can do some sort of geometric series thing.
gollark: Perhaps. Although you MAY need to do more things before you can consider them "learned".
gollark: Yeeees.
gollark: As h gets closer to 0, ((6+h)²-36)/h gets closer to something.
