	Tilting train - Wikipedia, the free encyclopedia
		The train may be constructed such that inertial forces themselves cause the tilting, commonly referred to as passive tilt, or it may be actively induced by a computer-controlled mechanism, referred to as active tilt.
		The first tilting trains were the TALGO trains of Spain, developed in the 1930s as a lightweight, fast train using passive tilt.
		Modern tilting trains have the blessing of the latest signal processing technology which reads the line ahead and is able to anticipate a very precise control signal to the individual carriages and complaints about nausea have become a thing of the past.

	High-speed rail - Wikipedia, the free encyclopedia
		The world speed record for a conventional wheeled train was set in 1990 by a French TGV (train à grande vitesse; literally "high speed train") that reached a speed of 515 km/h (320 mi/h), and an experimental Japanese magnetic levitation (maglev) train has reached 581 km/h (361 mph).
		The earliest high-speed train deployed in Europe was the italian "Direttissima" that connected Rome with Florence (254 km,158 mi) in 1978.
		The licitation is to be released in autumn 2005.

		Although the world speed record for a wheeled train was set in 1990 by a French TGV which reached a speed of 515 km/h (320 mph), the experimental Japanese magnetic levitation train has reached 581 km/h.
		The Eurostar trains which run through the Eurotunnel between the United Kingdom and France and Belgium are modified versions of the TGV trains, which are capable of running on different power systems and also with seven different signalling modes.
		These trains tilt, because of curves along the track, and the top speed is 150 mph (240 km/h).

	Comfort monitoring system and method for tilting trains - US Patent 6397129 (Site not responding. Last check: 2007-11-07)
		Tilting the body of a rail passenger car during curve negotiation offers the possibility of increasing the speed of a trainset in a curve without exceeding the maximum allowed steady state lateral acceleration felt by the passengers.
		Tilting of the car is accomplished by a servo-valve controlling the hydraulic mechanism, which in turn tilts the car.
		Tilting on wrong side (inverse tilt): the tilting command S3 and the lateral acceleration S4' have the same polarity a or -a is chosen as limit value.

		As early as the 1930s, automobile travel had begun to cut into the rail passenger market, somewhat reducing economies of scale, but it was the development of the Interstate Highway System and of commercial aviation in the 1950s and 1960s that dealt the most damaging blows to rail transportation, both passenger and freight.
		There was little point in operating passenger trains to advertise freight service when those who made decisions about freight shipping traveled by car and by air, and when the railroads' chief competitors for that market were interstate trucking companies.
		The only states which are not served by Amtrak trains are Alaska (served by the Alaska Railroad), Hawaii, South Dakota, and Wyoming (lost service in the 1997 cuts; served by Amtrak's Thruway Motorcoaches).

	Tilting Trains
		Trains that tilt can go up to 25% to 40% faster around curves than conventional trains without upsetting the passengers, and as mentioned before this can significantly increase average speeds and cut journey times.
		Clearly trains themselves need to tilt, then you get the double benefit of tilted track and tilting train, and the train can tilt to exactly suit the speed it is going at.
		While the very high speed trains like the TGV could be regarded as the Rolls Royce of trains, tilting trains could be thought of as the cheep and cheerful mini metro.

	Tilting trains shorten transit time (Site not responding. Last check: 2007-11-07)
		The trains are called Pendolino, or "little pendulum," because they automatically tilt the passenger cars by means of hydraulic or electromechanical tilt actuators—depending on operational requirements—connected to the wheel assemblies, or bogies, when negotiating curves at any speed.
		As a result, the train can negotiate curves at up to full speed, which is 35 to 45 percent faster than conventional trains without any effect on the quality of the ride.
		When a Talgo pendular train enters a curve, the higher placement of its springs creates a compressive force on the interior plane of the springs, tilting the train car to the inside of the curve by as much as 3.5 degrees.

	The Advanced Passenger Train
		The Great Success of the Diesel High Speed Train, the Inter City 125 causing a surge in demand lead British rail to want to develop a new high speed train for the northern sections, which were all stuck in the 100mph zone.
		This was an unusual period, because the fastest train in the UK was a diesel.
		This was a full sized proper train with passenger accommodation and actually served the London-Glasgow line for a period, although unreliability hampered its operation, and because of braking problems it had to be withdrawn.

		LONDON -- Britain's Virgin Trains on Tuesday (April 30) indefinitely shelved plans to run its new tilting trains at top-speed from London to Scotland, saying the line would not be able to cope despite a multi-billion pound upgrade, according to a Reuters report.
		The firm, which had intended to run its state-of-the-art Pendolino trains at 140 miles per hour, said it was pressing the government for hundreds of millions of pounds in compensation for the speed restriction.
		Virgin Trains, chaired by serial entrepreneur Richard Branson, runs the west coast main line route between London and Scotland, which is Europe's busiest and is currently undergoing a multi-billion pound, and much delayed, modernisation.

	Railway Technology - X2000 Tilting Trains operated by Swedish State Railways (SJ), Sweden
		Sweden's X2000 fleet of tilting trains has been a major catalyst for the renewed interest in this type of technology shown by the newly-privatised British train operators investing in the final years up to the millenium.
		Each train also has three independent braking systems, an electric regenerative brake for speed adjustments down to standstill; air-operated disc brakes for normal and hard braking, and a magnetic track brake for use in emergencies.
		The trains' tilting mechanism brings long-term benefits for the track in the form of reduced forces, cutting down on wear, which in turn allows speeds to be increased substantially on straight track, and by up to 50% through curves.

		QUEENSLAND Rail's Cairns Tilt Train (CTT) was constructed at Walkers' facility in Maryborough, Queensland, by the QR-EDI/Walkers Rail Alliance which was responsible for design, procurement, manufacture, testing, commissioning and project management.
		This means that, together with the new tilting train, there are five services a week to Cairns (up from four a week), and a daily service to Townsville (up from six services a week).
		As there are no sleepers on the tilting train, this should ensure a continuing market for the Sunlander which is 6h 30mins hours slower.

		The trains have a top speed of 220km/h (135mph), and their tilting capability gives the potential for 30% higher speeds through curves, which RENFE calculated would give an initial 18 minute saving on the previous journey time of just over three hours 50 minutes.
