TAYLOR WOODROW Norwich Crown Point Depot

Location: Norwich, UK

Expertise Areas: Architecture

DB3 is providing support to Taylor Woodrow on the upgrade of Norwich Crown Point depot, where we are tasked with designing various extensions, upgrades, and refurbishments for client, Greater Anglia.

We have been appointed as Architects and Principal Designer for the creation of a new Bogie Store facility. These works aim to extend the existing facilities to accommodate the servicing, maintenance, and stabling requirements of a new fleet of 58 trains being manufactured by Stadler.

The introduction of a new bogie drop installation was successfully completed in early 2021 to cater to the unique low-floored design of the trains, ensuring improved accessibility for passengers. The majority of train components are located on the roofs, which necessitates special high walkways to be integrated into the facilities.

The new Bogie Store is designed to complement the recently completed bogie drop facility. It provides ample storage space for 18 bogies and 20 wheel sets, and features an overhead crane for efficient operations. Moreover, the facility includes supporting office accommodation to facilitate the smooth functioning of the depot upgrade.

Norwich Crown Point Headshunt

Location: Norwich, UK

Expertise Areas: Architecture

Greater Anglia is introducing a new fleet of trains and, to support their operations, an expansion project is underway at the Norwich Crown Point Depot.

The project includes constructing an additional Headshunt line and Fatality Wash parallel to the existing line. These additions will facilitate hand bashing, sanding, graffiti wash, CET servicing, fatality inspection, and wash procedures for the new trains. A welfare facility will also be established to support cleaning and inspection operations.

DB3 is appointed to fulfill the roles of Lead Design Organisation (LDO) and Principal Designer.

The site, on the East side of the Norwich Crown Point Depot, runs adjacent to the existing carriage wash bypass line. The new Headshunt line will be parallel to the existing one, with a concrete walkway in between for CET servicing, water, sanding, and hand bashing. Another walkway south of the new line is proposed for hand bashing.

The Fatality Wash will be positioned at the front of the new line to allow efficient cleaning and inspection. A staff welfare unit will cater to male and female staff, providing changing rooms, washing facilities, toilets, and a small food prep area while ensuring contamination segregation.

To address site constraints, a prefabricated modular solution will be used, considering neighbouring structures.

Care will be taken to avoid any adverse impact on the existing carriage wash facility on the adjacent line by situating the Fatality Wash close to the carriage wash hardstanding without affecting the existing transfer slab.

Clacton Depot Upgrades

Location: Essex, UK

Expertise Areas: Architecture

In the Clacton Depot Upgrades project for Greater Anglia Rail, DB3 played a crucial role as the Lead Design Organisation (LDO) representing Taylor Woodrow.

DB3’s main focus was on implementing Glass Reinforced Plastic (GRP) walkways and relocating Controlled Emission Toilet (CET) and Water connections. Additionally, step platforms were incorporated to ensure the safety of individuals accessing the trains.

To further ensure the safety and convenience of personnel accessing the trains, lighting bollards were incorporated into handrail sets outs. DB3 worked closely with a lighting expert to ensure that the lighting was sufficient for visibility without adversely affecting the train drivers. One of the major challenges faced by DB3 was navigating overhead lines while installing the GRP walkways and platforms. Safely managing the overhead lines was critical to prevent any accidents or disruptions to the rail services. Additionally, gauging testing was carried out to ensure that all installed structures complied with the necessary standards and provided smooth train operations.
