Comet is a pinball machine released by Williams in June 1985. It was designed by Barry Oursler and was the first in an amusement park themed pinball trilogy followed by Cyclone in 1988 and Hurricane in 1991. In this pinball game, the player attempts to navigate throughout a representation of a Carnival, with the namesake Comet being a central ramp representing a roller coaster worth 10,000 points. Two banks of Shooting Gallery targets can be targeted to score points and advance the matching bonus counter; each bonus track is worth a maximum of 63,000 points. Hitting all four targets in a target bank lights an additional objective, which allows the player to collect the matching bonus during play by completing the Whirlwind ramp or the Funhouse saucer. Completing both target banks lights additional points for the center ramp, including the chance for extra balls and replays depending on specific game settings. Completing the ramp advances both bonuses; the most definitive feature of Comet is a Motorcycle Jump ramp on the upper-right side of the playfield.

This features a Skee ball-like scoring setup, where the closest target is worth 20,000, the middle target is worth 50,000, the farthest target is worth 200,000. Completing the ramp advances both bonuses; the ramp starts each ball in a lit state becomes unlit after being scored. Comet features a unique flipper area arrangement. On the right side, there is no inlane and on the left side, the inlane and outlane are inverted. What would be an inlane on a conventional pinball machine instead causes the ball to drain; the left inlane relights the Motorcycle Jump ramp, the two outlanes advance the bonus. Next to the central Comet ramp is a drop target. Once the drop target is hit, the dummy will taunt the player using voice sounds. Hitting the Dunk The Dummy target will increase the bonus multiplier by one step. At the top of the playfield is a set of four rollover targets that spell out 1-9-8-6. Completing these four targets will activate a playfield point multiplier for a limited time. By default this is a 2x multiplier, but is 3x on the second ball, 5x on the final ball.

Comet provides the ability to cycle the lit targets towards the right by activating the right flipper, using the Lane Change feature. If the 5x playfield multiplier is lit at the same time as the Motorcycle Jump ramp is lit, a voice will announce "One Million!" and additional playfield lights will highlight the Motorcycle Jump ramp. Completing the longest jump at this time will award one million points. Comet was the first solid-state machine to feature a one million point shot.

The Yorkshire and Humber Route Utilisation Strategy is a Route Utilisation Strategy, published by Network Rail in July 2009. By default, RUSs are established by the Office of Rail Regulation unless the latter objects within 60 days; the RUS is included in NR's map as established. The scope corresponds with Strategic Routes 10 and 11; the Y&H RUS picked up several issues from other RUSs, specifically: Freight RUS, throughout the RUS area North West RUS as regards the Calder Valley, Hope Valley and Huddersfield corridors East Coast Main Line RUS at Wakefield Westgate, Doncaster and York Lancashire and Cumbria RUS as regards the Airedale and Calder Valley corridors the Network RUS, Electrification workstream the former Strategic Rail Authority’s Midland Main Line RUS. Issues in the Y&H RUS were relevant to the East Midlands RUS at Chesterfield and in Lincolnshire; as with other RUSs, the Y&H RUS took into account a number of responses, including the Office of Rail Regulation. The routes and services covered by the RUS are varied in type.

Many lines are used for passenger services with little, if any, freight. A number of passenger transport executives have significant influence over transport planning in the area; some issues were passed to Electrification workstream. The RUS needs to be seen against existing contingent and prospective schemes in Control Period 4; the RUS identifies generic groups of gaps and issues Peak crowding Overcrowding on peak time trains into Leeds and Sheffield Off-peak crowding Overcrowding between the peaks leading to suppression of demand Engineering access Closure of routes for engineering access leading to suppression of demand Regional links Connectivity within the RUS area, between the RUS and external areas Freight capability Lack of availability owing to inadequacy of diversionary routes, route availability, loading gauge and/or capacity Reactionary delays Reactionary delays contributing to poor performance. A number of routes and services suffer from overcrowding of passengers in each 3-hour peak periods.

In all cases these problems are foreseen, in the absence of interventions, to get worse owing to forecast growth in passenger traffic. These are referred to as "peak crowding" in the detail below. In March 2009 Network Rail published its CP4 Delivery Plan 2009, including Enhancements programme: statement of scope and milestones, confirming most of the recommended interventions. Specific projects, scheduled to cost about one billion pounds in total, with their reference and page numbers in the document, are given below: 03.05 Strategic Freight Network, Train lengthening projects fund, regarding Hope Valley, p24 18.01 Capacity relief to the ECML, pp94–95 18.07 York Holgate Junction 4th line, p106 18.08 Shaftholme Junction re-modelling, pp107–108 19.00 Overhead line electrification refurbishment, pp111–112 23.00 Northern urban centres - Yorkshire, p125 23.01 Capacity improvements, pp126–8 23.02 South Yorkshire - train lengthening, p129 23.03 South Yorkshire - stabling for Northern, p130 25.00 Trans-Pennine line speed improvements, p137
