300

On 13 January 1897, Walkers Limited completed their first steam locomotive, with a very successful trial run to Howard and return. This engine became known as a B15 class 4-6-0 tender design, and allocated QR No. 299, Walkers Limited works No. 1. The 'B' signifies three driving axles and the '15' is the cylinder diameter in inches. The Walkers Limited design was similar to that of locomotives imported from England, but they were fitted with much-improved cabs and were the first engines built for the Queensland Railways to come ready fitted with the Westinghouse automatic brake system. Builders plates were fitted to each side of the tender as well as each cab side, and in addition, a large circular maker's plate (complete with 5 point star and the words 'Walkers Limited Engineers') was carried on the smokebox door similar to early American engines.

Parseval was the name of the designer, and there were 22 such ships built. This one could be the PL-18 No. 4

The biplane at front right, No. 235 is identified as a BE.2a here: www.ukserials.com/serials-older-000.htm It is a Royal Aircraft Factory (Blériot Experimental) en.wikipedia.org/wiki/Royal_Aircraft_Factory_B.E.2

artolog, Thank you very much for such in depth digging about the airship and the accompanying plane - and for providing great citations. We'll add more identifying information when we update this record.
