LED: Brecon Mountain Railway

The Brecon Mountain Railway is a tourist railway with steam locomotives on the south side of the Brecon Beacons. The line runs along part of the trackbed of the northern section of the former 4 ft 8 1/2 in (1,435 mm) standard gauge Brecon and Merthyr Railway from Pant to a new station at Torpantau, via Pontsticill and Dolygaer, a total of about 4.5 miles (7 km).


The Brecon Mountain Railway parks their steam locomotives in a purpose-built building, which includes a workshop and viewing gallery.

The light levels were very poor and staff needed additional lighting. Additionally, the public’s view and experience was negatively affected.

Electricity costs were high due to the old, inefficient lighting, and maintenance was also a safety concern due to the height and floor configuration.

Upgrading lighting

Brecon Mountain Railway (BMR) line runs from Pant, 3 miles north of Merthyr Tydfil, to Torpantau. It follows part of the route of the original Brecon & Merthyr Railway, which closed in 1964. The tourist attraction offers rides on steam locomotives through the Brecon Beacons National Park.

Ineco Energy upgraded the lighting within the engineering workshop, and internal steam-train parking sheds. The heat and vapour from the steam trains presented a unique challenge for the design team. As well as regular testing, the engines regularly use full steam mode while parking or pulling out of the sheds.


The survey, design and installation took place in an environment which included floors with different levels, pits, gradients and large cranes; all required to design, repair and maintain the steam trains. Detailed Health & Safety planning ensured BMR’s operation wasn’t disrupted during the installation, while live railway tracks meant additional staff safety challenges.

Ineco Energy secured grant and loan funding from the Carbon Trust Green Business Fund for Brecon Mountain Railway, so the capital cost was significantly reduced.


Brighter, more efficient lighting delivered increased light levels for the BMR maintenance teams. Light levels were significantly increased from 200lux to 750lux. A 5-year parts and labour warranty for the bespoke lighting design and installation delivered peace of mind for the management of BMR.

"Light levels are so good that we don’t need additional lighting and our visitors can see all the activity within the workshop. Our safety risk is also improved because we won’t have to get up and replace the bulbs every year.”
