The South Devon Railway is able to supply copper sheets large enough to construct new locomotive fireboxes! Satisfied customers now include the Paignton & Dartmouth Railway whose newly recommissioned locomotive, 7827 Lydham Manor, recently returned to traffic with a new firebox made from copper sourced and supplied via the SDR workshops at Buckfastleigh.
 
 

The copper sheets come in the following sizes:-

10' x 8' x 5/8"
&
8' x 6' x 1"

The copper is to  C107 (BS 2875)  Phosphorous Deoxidised Arsenical Copper and is from a European source.

Another heritage line is about to take delivery of four sheets being sufficient to construct a firebox for one of their locomotives.

Enquiries should go in the first instance to Rob Le Chevalier at Buckfastleigh Works. 01364 643461
