| 摘要： | Having been involved at the Trolleybus Museum at Sandtoft for many years, including doing most of the in-house MoT inspections, I feel I can respond with reasonable confidence to Robin Hannay's questions about Walsall trolleybus 342 (You Write, January). Much of general manager Edgley Cox's work in the 1950s was focused on making vehicles lighter for the same or a larger payload. A weight-saving feature (of at least 10cwt) in the mechanical specification of the pioneering two-axle 30ft Sunbeam F4As of 1955/56 was their Lockheed high-pressure hydraulic braking system; 342 also has hydraulic brakes. |
