The London DM and DMS Buses - Two Designs Ill Suited to London


Book Description

JIM BLAKE'S latest book on London's buses may come as a surprise, since he usually concentrated on older vehicles in the fleet. However, the unpopular, unsuccessful DMs and DMSs were still part of London Transport's history, so he recorded them too, particularly towards the end of the short working lives. Forced by central government to buy "off-the-peg" standard manufacturers' products, rather than their own tried and trusted designs, LT opted for Daimler Fleetlines for their first fleet of one-man-operated double-deckers. Optimistically christened "Londoners" when they first entered service in January 1971, they instantly became unpopular with passengers, staff and bus enthusiasts alike. Their square, box-like appearance and bland all-over red livery did not endear them to the latter. Passengers used to boarding buses immediately with fares collected or tickets checked by a conductor objected to waiting at termini until the driver appeared and opened their doors, and having to queue at stops waiting to pay as they entered. Automatic ticket machines meant to mitigate this broke down making matters worse; all this increased journey times. The vehicles had flimsy bodywork, easily damaged by the slightest collision, and were also mechanically unreliable: their rear engines often caught fire. This made them unpopular with drivers and maintenance staff. Although the type worked satisfactorily in the provinces, it was just not suited for the rigors of London service. This book presents a selection of pictures of them, many previously unpublished and also graphically illustrating the buses' many defects.

The London DMS Bus


Book Description

Vilified as the great failure of all London Transport bus classes, the DMS family of Daimler Fleetline was more like an unlucky victim of straitened times. Desperate to match staff shortages with falling demand for its services during the late 1960s, London Transport was just one organization to see nationwide possibilities and savings in legislation that was about to permit double-deck one-man-operation and partially fund purpose-built vehicles. However, prohibited by circumstances from developing its own rear-engined Routemaster (FRM) concept, LT instituted comparative trials between contemporary Leyland Atlanteans and Daimler Fleetlines.The latter came out on top, and massive orders followed. The first DMSs entering service on 2 January 1971. In service, however, problems quickly manifested. Sophisticated safety features served only to burn out gearboxes and gulp fuel. The passengers, meanwhile, did not appreciate being funnelled through the DMS's recalcitrant automatic fare-collection machinery only to have to stand for lack of seating. Boarding speeds thus slowed to a crawl, to the extent that the savings made by laying off conductors had to be negated by adding more DMSs to converted routes! Second thoughts caused the ongoing order to be amended to include crew-operated Fleetlines (DMs), noise concerns prompted the development of the B20 ‘quiet bus’ variety, and brave attempts were made to fit the buses into the time-honored system of overhauling at Aldenham Works, but finally the problems proved too much. After enormous expenditure, the first DMSs began to be withdrawn before the final RTs came out of service, and between 1979 and 1983 all but the B20s were sold – as is widely known, the DMSs proved perfectly adequate with provincial operators once their London features had been removed. OPO was to become fashionable again in the 1980s as the politicians turned on London Transport itself, breaking it into pieces in order to sell it off. Not only did the B20 DMSs survive to something approaching a normal lifespan, but the new cheap operators awakening with the onset of tendering made use of the type to undercut LT, and it was not until 1993 that the last DMS operated.

The London Enviro400


Book Description

Developed by Alexander Dennis in 2005 as an all-encompassing replacement for the Dennis Trident and its two bodies, the Plaxton President and Alexander ALX400, the integral Enviro400, immediately sold in large numbers, not least to London operators, which in the next eight years bought over 1,500 of them. Late in the production run, the hybrid E40H was introduced and also made good headway in London, funded largely by environmental grants. Nearly 300 of these are in service in London.Valid to May 2015, this book finishes by introducing the MMC, the all-new development of the Enviro400 unveiled in 2014 and exemplified in London so far by two batches for Abellio and Metroline.




The 2030 Spike


Book Description

The clock is relentlessly ticking! Our world teeters on a knife-edge between a peaceful and prosperous future for all, and a dark winter of death and destruction that threatens to smother the light of civilization. Within 30 years, in the 2030 decade, six powerful 'drivers' will converge with unprecedented force in a statistical spike that could tear humanity apart and plunge the world into a new Dark Age. Depleted fuel supplies, massive population growth, poverty, global climate change, famine, growing water shortages and international lawlessness are on a crash course with potentially catastrophic consequences. In the face of both doomsaying and denial over the state of our world, Colin Mason cuts through the rhetoric and reams of conflicting data to muster the evidence to illustrate a broad picture of the world as it is, and our possible futures. Ultimately his message is clear; we must act decisively, collectively and immediately to alter the trajectory of humanity away from catastrophe. Offering over 100 priorities for immediate action, The 2030 Spike serves as a guidebook for humanity through the treacherous minefields and wastelands ahead to a bright, peaceful and prosperous future in which all humans have the opportunity to thrive and build a better civilization. This book is powerful and essential reading for all people concerned with the future of humanity and planet earth.
