Data from the Queensland Railways Interest Group's website at [], last accessed 21 January 2012. Works numbers were 16 in June 1894, 17 in July, 18 in November, and 19-23 in 1895 (January, March, June, September, and December, respectively).
The QRIG explain that the A14 was an enlarged version of the earlier American-influenced A12 and showed an increase in trailing load of 45 tons (54 short tons) over the earlier engines. They hauled the passenger and mail trains between Brisbane and Ipswich some 40 km (25 miles) away.
They were reboilered in 1909; see Locobase 13759.

Locobase 13758 shows the A14s as they were delivered. The QRIG website does not spell out why, but 15 years after they entered service, the class received new boilers and new fireboxes. Both were bigger, although the firebox's grate area shrank slightly in the redesign.
By this time, 281, 285-286 had been transferred to the Central District. A few were used to operate the Belmont Tramway in southeastern Brisbane from 1916 to 1924. The last service use for the 283-284, 287-288 was to haul the Poison Trains, which roamed up and down QLD tracks spraying poison on the weeds that grew between the rails. The Australian blog Australian Song a Day entry for 19 December 2011 ([], last accessed 201 January 2012) reproduced a Mick O'Rourke song called Poison Train that emphasizes the lethality of the service in two of its stanzas:
"still hear the tall man say?
To the children at their play
'You'd better go home early?
And you'd better stay away
Stay away from the line?
Can't you hear the railway humming?
The grass has grown too tall
And the poison train is coming
You feel sorry for the grass?
All it did was grow too fast?
All the weapons used against it?
It was never made to last?
And the man and his offsider
Are all dressed in black?
As the poison train goes through the town
And blisters all the track"
The first of the A14s retired in 1922, the last in 1930.
