Stewarts Lane railway depot in Battersea has been providing maintenance and stabling for the South East of England’s rolling stock since 1862 and was, at one point, the largest locomotive capacity in the Southern region. Having stabled the Royal Train, one of the depots main uses today is for the maintenance of the prestigious Orient Express.
After the installation of a Nor-Ray-Vac system 28 years ago in the high bay and main locomotive shed at Orient Express, the system needed to be replaced.
Entrance and exit doors occupy the full width of the building and may be left open for many hours a day. When doors are open at both ends, a wind tunnel effect is created, and cold air at high velocity is drawn into the shed. Keeping the shed warm enough for employees to work in comfortably is compounded by the often north-south alignment of the tracks, which allows very little sunshine to warm the interior.
Reznor was able to offer an effective and economic heating solution. Blanket heat coverage was not a necessity in the rail shed as only the areas where personnel are working needed to be heated. When operatives are working on one part of the train, zoning enables all other parts of the radiant heating system to be switched off. This produces considerable fuel economies and cost reductions.
Economy and effectiveness were the two key criteria when selecting the heating system for the shed. One form of space heating technology ideally suited to this cold and inhospitable working environment is the Nor-Ray-Vac radiant tube heating system.
Reznor replaced the old system with the latest Nor-Ray-Vac series system which was happily received by the client due to the past financial benefits of this type of heating system.
The project was completed in three stages. Phases One and Two are where the complete rebuild of the carriages takes place for the trains and were previously unheated bays.
An area of 41 x 15m and 7m-high, saw the installation of a Nor-Ray-Vac system consisting of 6 x 24kW burners with one flue discharge.
An area of 30 x 15m and 7m-high, saw the installation of a Nor-Ray-Vac system consisting of 6 x 18kW burners with one flue discharge.
This is the high bay and main locomotive shed where the steam locomotives are maintained on a regular basis. The Nor-Ray-Vac system was an exact replacement of the original to minimise the installation costs. In the high bay area, 30 x 20m and 12m-hig,h a Nor-Ray-Vac system of 10 x 18kW burners with one flue discharge was installed going around the perimeter of the bay, below the crane beam. In the main locomotive of area 77 x 15m and 7m-high a received a Nor-Ray-Vac system consisting of 18 x 18kW burners was arranged in three zones with two flue discharges.
The Nor-Ray-Vac system combusts the fuel at the point of use enabling maximum efficiency with no distribution losses and has rapid response to changed conditions. It is uniquely designed to accommodate the building constraints and required zoning for the method of working within the shed. The flexibility of the radiant heating system meant that specific areas can be heated as required by the work patterns within the shed, keeping staff warm.
The client employed Multigas to undertake the new and replacement works.
Orient Express now benefits from a radiant heating system capable of maintaining the depot at a comfortable environment well into the late 2030’s.
