Case Study - Class 43 HST Cab Sunblind

Background

When GNER had problems with their HST (Class 43) cab environment, they came to ESG, the company supporting the largest fleet of locomotives in the country for DB Schenker Rail.

The Class 43 sunblind design was 40 years old, and is similar in design to that seen on many of the older units operating across the UK. The HST operator was suffering from numerous instances of the blind unexpectedly releasing from the stowed position and striking the driver on the head. A change had to be made quickly, and GNER identified ESG as the company to deliver.

Outcome

ESG completed the HST (CL 43) design, first fit, and fitting procedure on time to meet GNER requirements. ESG also achieved on time delivery of sunblinds for First Capital Connect's fleet of CL 317.

Benefits

ESG sourced a new blind to solve the initial problem, but also provided numerous additional improvements including:

  • Increased screen coverage
  • Better sun protection
  • Spring retraction

Project Overview HST (CL43)

ESG provided a prototype fitment using existing mounting points to minimise installation downtime, and this was immediately approved by the drivers. It has since been reported as a huge improvement in design, increasing visibility of the line and significantly reducing temperature build-up in unoccupied cabs.

ESG also managed the full approval route (with Railway Approvals Ltd.), promoting the most economical and up-to-date option to the operator; resulting in this modification being the first GNER/NXEC modification to be approved via the NoBo/Competent Person route.

Increasing Range of Sunblinds

ESG have since developed the sunblind range in recognition of the numerous vehicles on the network with old fashioned sun visors, and can offer sunblind design, kit supply, installation, and approval to suit a wide range of applications with short implementation timescales.
