Manchester & Milford 2-4-0 Locomotives in Great_Britain
Class Details by Steve Llanso of Sweat House Media
Class Carmathen (Locobase 21093)
Data from Graham Davies at members.tripod.co.uk/Graham_Davies/index-51.html. See also "Railways in West Wales Part 1B - Pembrokeshire - the Mainline Railways" on Roger Farnworth's blog at [
], last accessed 22 September 2022. Works numbers were 1713 and 1756 in 1866.
Locobase 4898 shows the Pembroke & Tenby #3, which duplicated the standard Sharp, Stewart six-wheel passenger engine design. Davies wrote that the P&T was to take two of three in the order with the other going to the M&M. But the P&T only operated one of the the three. Martin Coombs's builders list shows the 1713 as the first in SS order E485 and 1756 (named Lady Elisabeth) as the second.
