List of Queensland steam locomotives
List of Queensland steam locomotives[1]
Classification
The classification system use by Queensland Railways consisted of a letter, indicating the number of driving axles, followed by a number, indicating the cylinder diameter in inches. This was confusing for two reasons: (1) it differed from the international system and (2) it could lead to several classes having the same classification number. Where classification numbers were duplicated, the classes were usually distinguished by the name of the builder, e.g. A10 Baldwin, A10 Fairlie, A10 Neilson.
| Number of driving axles | International classification | QR classification |
|---|---|---|
| 1 | A | - |
| 2 | B | A |
| 3 | C | B |
| 4 | D | C |
| 3 (Tank locomotive) | D |
Improved versions of a similar class were given a second identical letter. For example, the improved version of the D17 was the DD17.

Ipswich workshops
The old Ipswich workshops of Queensland Railways built locomotives up to 1879 when a Select Committee recommended that no further locomotives be built there. The new Ipswich workshops began building locomotives in 1903.[3]
