2D-142-001 DAPOL N GAUGE CLASS 142 RAILBUS NUMBERED 142096 IN NORTHERN RAIL BLUE/PURPLE/WHITE (DEBRANDED) DCC READY. A BRIEF HISTORY OF THE MODEL. The British Rail Class 142 diesel multiple-unit passenger railbuses were built for British Rail (BR) from 1985 to 1987. The class were built with a high level of commonality with the widely-used Leyland National bus.
They are part of the Pacer family of railbuses. The last set was withdrawn from service in 2020. By the beginning of the 1980s, British Rail (BR) operated a large fleet of first-generation DMUs, which had been constructed in prior decades to various designs. In the light of the high costs involved in retention, planners examined the prospects for the development and introduction of a new generation of DMUs to succeed the first generation. In the concept stage, two separate approaches were devised, one involving a so-called railbus that prioritised the minimisation of both initial (procurement) and ongoing (maintenance & operational) costs, while the second was a more substantial DMU that could deliver better performance than the existing fleet, particularly when it came to long-distance services.
While the more ambitious latter requirement would ultimately lead to the development of the British Rail Class 151 and the wider Sprinter family of DMUs, BR officials recognised that a cheaper unit was desirable for service on the smaller branch lines that would not be unduly impacted by lower performance specs or a high-density configuration. Work to progress both approaches was therefore undertaken by BR's research department during the early 1980s. During this period, a number of prototypes were constructed to explore different designs and approaches for implementing the railbus concept. One such vehicle was a single two-car unit, designated Class 140, built between 1979 and 1981.
This prototype was introduced with much fanfare in June 1981. Initial testing with the Class 140 uncovered several problems, such as difficulty detecting the type via track circuits.
This was reliably resolved by changing the material of the brake blocks from a composite to iron. Two less easily addressable drawbacks were the high level of noise generated during transit, particularly on older jointed rails, a consequence of the railbus's direct connection between the underframe and suspension with the body that transmitted impact forces across the body.
It was also observed that the inclusion of strengthening members in the mass-produced bus body added significantly to the overall production cost, which eliminated much of the cost advantage that was the primary goal of the type. The Class 140 was deemed an overall success, so BR issued an order for an initial production model, designated Class 141, to British Leyland during 1984. During its early years of service, the Class 141 experienced numerous problems, particularly with the transmission and ride quality; work undertaken by BR resulted in the quick development of numerous improvements to at least partially address these shortcomings. When it came to ordering more railbuses, however, it was decided that instead of placing these follow-on orders for further Class 141, it would be more desirable to procure improved derivatives of the Class 141. Accordingly, BR placed orders for two new models of the Pacer family with separate manufacturers, these being the Class 142 and the Class 143.WHATS INCLUDED WITH THE MODEL.
