We are proud to present the iconic Quarry Hunslet as the launch locomotive for the new Bachmann Narrow Gauge NG7 Scale range. Depicting ‘Una’, built originally for the Pen-yr-Orsedd Quarry but now residing at the National Slate Museum, this new model builds on the success of its smaller, award-winning Bachmann Narrow Gauge OO9 scale cousin. The larger NG7 scale affords a higher level of detail, along with an enhanced technical specification which includes a Next18 DCC decoder socket, pre-fitted speaker and firebox lighting system, all of which is fully utilised in this SOUND FITTED model.

With a diecast metal chassis and gearbox, coupled with a precision moulded plastic bodyshell, cylinder block, frames and footplate, the 0-4-0ST wheel formation is faithfully modelled, with authentically profiled wheels running in metal bearings which ensures smooth running. A wealth of separately fitted detail parts complete the model, including handrails, valves, springs, brake shoes and cab controls. All of this is finished with a high-fidelity livery application, using the latest techniques to capture every aspect of the prototype’s decoration. Coupling solutions provided with this new NG7 model include two types of chopper coupling and the hook and loop type used on Bachmann Narrow Gauge OO9 scale models – all of which attach via the NEM coupling pockets.

QUARRY HUNSLET ‘BRITOMART’ HISTORY

The Quarry Hunslet locomotives were built by the Hunslet Engine Company of Leeds. Rather than denoting a single design, the term Quarry Hunslet refers to several different locomotive types, each built to a similar design, but with specifics suited to their intended use. The first Quarry Hunslets were the Penrhyn Port Class, built for shunting duties at Port Penrhyn, the coastal port of Penrhyn Quarry – once the largest slate quarry in the world. These locomotives sported a 4ft wheelbase and the first example was delivered in 1883.

In 1886 the nearby Dinorwic Quarry, Wales’s second largest slate quarry, took delivery of its first Quarry Hunslet, named ‘Velinheli’. Smaller than the Penrhyn locos with a wheelbase of just 3ft 3in, the second Dinorwic loco, delivered in 1889 and originally named ‘Alice’, would lend its name to the locomotive type and by 1904 eleven Alice Class Quarry Hunslets had been delivered to the Dinorwic Quarry. All were built to fundamentally the same design, although details inevitably changed over the years, but a notable feature of the Alice Class locos was the angled frames and resulting shallow bufferbeams at the front and rear. At the quarry the locomotives were moved between the various galleries and to and from works via the steep inclined planes – straight frames would bottom out on these steep inclines, a problem avoided by building the locos with angled frames.

Five similar locomotives were built for use at Port Dinorwic during the same period, these shared much the same design as the Alice Class locos but had straight frames which resulted in them sporting much deeper bufferbeams. The Alice Class also provided the blueprint for six more engines which were built for smaller concerns; the Pen-Yr-Orsedd Quarry which took three, Moel Tryfan Quarry had two, and a single example was delivered to the Dorothea Quarry. The Penrhyn Quarry placed orders for four of these smaller 3ft 3in. wheelbase locomotives too – these became known as the Penrhyn Small Quarry Class to avoid any association with their rivals the Dinorwic Quarry. Penrhyn Quarry would later order another six Quarry Hunslets, but these reverted to the 4ft wheelbase used on the Penrhyn Port Class locos; whilst very similar in design, this final batch of Quarry Hunslets were different enough to be known instead as the Penrhyn Large Quarry Class.

‘Una’ was the last of the three locomotives built for the Pen-yr-Orsedd Quarry. Works number 873, she was delivered in 1905, following ‘Britomart’ which was built in 1899 and ‘Sybil’ in 1903. Built with an enclosed cab, ‘Una’ was employed at the quarry in the Nantlle Vale, North Wales until withdrawal in 1960. In 1965 ‘Una’ was sold and ten years later a major overhaul began. Two years later she was sold again, this time to the National Museum of Wales for use at the National Slate Museum, and the following year in 1978, her overhaul was completed. Returning to traffic in lined green livery, in 2007 ‘Una’ was repainted into a dark red colour scheme, harking back to be the livery she carried when first delivered to the Pen-yr-Orsedd Quarry. Today, work is underway to overhaul the locomotive.
