At some point in the early 1950s, the well-known Welsh engineering firm of Taffson, Evans & Jenkins decided to close their rail-connected factory in the suburbs of Cardiff and concentrate their production in their two remaining facilities in the Rhondda Valley and South Gloucestershire.
Taffsons removed all engineering equipment and all other plant and materials before they vacated the premises and the factory buildings in the Rumney area lay empty for a number of years and although the Private Siding Agreement with British Railways was legally terminated, the physical rail connection was never actually removed.
Eventually in the late 1950s, a new owner bought the now semi-derelict buildings, with a view to redevelopment for residential and light industrial use.
The demolition contractors moved in and began to steadily level the site. Imagine the foreman's surprise, therefore, to be told after only being on site for a few days that the previous owners hadn't removed all the contents.
Hidden under a series of tarpaulins at the back of the former Assembly Shop were three old steam locos, all representing types previously thought lost, together with some heavy machine tools.
Even then, the future of the locos wasn't secure, because the foreman in his wisdom called his brother-in-law, who was a scrap contractor and offered them to him in exchange for an undisclosed sum of money. The scrappies turned up a week later with cutting gear and a large lorry. They made short work of the rusting machine tools but ran out of acetylene before they could start on the locomotives.
At this stage, Jonathan Greenhouse, an industrial archaeology student from the University of Aberystwyth visited the site to research his thesis on the history of manufacturing in Glamorgan. Mr Greenhouse had a hunch that these locos might be worth something and hurried away to find a public call box, to call his brother, the well-known and wealthy railway enthusiast P.B. Greenhouse.
Mr Greenhouse immediately realised the significance of the find from the descriptions provided by his brother and managed to find the telephone number of the Barry HQ of the scrap contractors.
The rest is, as they say, history. P.B. Greenhouse managed to purchase all three locos for little more than their scrap value and used his contacts within British Railways, Western Region to arrange for one of the Canton shed pilots and a brake van to be loaned one afternoon. Under the watchful gaze of the local PW inspector and the Divisional Operations Superintendent, the siding connection into the works was temporarily brought back into use and a Canton 57XX gingerly edged into the old Assembly Shop to collect the locos.
Hauled back into daylight for the first time in many years, the significance of the 'find' became abundantly clear to P.B. Greenhouse. Here was a former GW '517' 0-4-2T and two absorbed types of 2-4-0T, 'Lady Margaret' (formerly of the Liskeard & Looe Railway and ex-Cambrian tank loco No. 1197.
Mr Greenhouse had arranged for all three locos to be tripped to Caerphilly Works for overhaul, funded by himself and other private donors.
A few months later, a decision had been taken in conjunction with the directors of the Association of Independent Light Railways for the locos to be taken to Llanddewi on the Vale of Radnor Light Railway, where they would be kept and possibly used on service trains on that and also loaned out to other member railways.
The locos all travelled separately to Radnorshire, as they were not all overhauled at the same time.
The first to be moved was 'Lady Margaret', which was tripped to Ebbw Junction yard and then on a series of freights to Leominster, where she was marshalled in the daily goods working to Kington and Capel Bethesda. Here she is seen arriving in Bethesda yard behind regular branch loco 1458:
Note the resident VoRLR loco (ex-LNER J72 'Jennifer') waiting in the sidings to haul 'Lady Margaret' onto the Light Railway.
