Rationale

Airplanes and bicycles tilt in when cornering but automobiles and trains cannot do this on their own. Vehicles with high centres of gravity rounding sharp curves at high speeds may topple over, and banking helps counteract this risk. To make their turns easier, the outer edge of a roadway of a high-speed highway or outer rail of a railway is canted (raised) upward around the curve. To a passenger in such a vehicle the tilt makes the overall acceleration vector act downwards, relative to the passenger, rather than pushing them to the side, minimising discomfort.

The particular angle of tilt ("superelevation") is determined by the intended vehicle speed — faster speeds require more banking. But with a growing desire in the 1960s and 1970s to build high-speed rail networks, a problem arose: the amount of tilt appropriate for high-speed trains would be over-tilted for slower-speed local passenger and freight trains sharing the lines.

". Researchers have found that if the tilting motion is reduced to compensate for 80% or less of lateral apparent force passengers feel more secure. Also, motion sickness on tilting trains can be essentially eliminated by adjusting the timing of when the cars tilt as they enter and leave the curves. It was found that when the cars tilt just at the beginning of the curves instead of while they are making the turns, there was no motion sickness.

Many high-speed trainsets are designed to operate on purpose-built high-speed lines and then continue their journeys on legacy lines, upgraded or not. Where the legacy lines justify it, a tilting train may operate at higher speeds on the latter, even if below the normal 200 km/h (124 mph) threshold, whilst operating at 250 km/h (155 mph) or faster, usually with tilt disabled, on the high speed lines.

 wanted an advanced fast train to negotiate the UK's twisting and winding Victorian rail system. Conventional trains were limited in speed due to the twisting nature of the network. British Rail deliberately commissioned two young, bright, inventive engineers with no experience in trains or railways to head the development of the project. One had worked in missiles and the other for the National Coal Board. They worked in isolation to the in-house British Rail engineering team. The reason for total outsiders to develop the trains was that they would have no preconceived rail engineering prejudices and would approach the problem with a fresh open mind. These fresh minds brought to trains methods and technology from other advanced fields. They brought science into British railways, an industry that from its quantum leap in innovative technology in the Victorian times, had advanced at a snail's pace ever since.
The by-passed in-house British Rail design engineers poured scorn on the project, nevertheless the new engineers used their inventiveness to progress the project. The project engineers experimented with aluminium bodies, turbines, new suspension and bogies and active tilt to negotiate the British rail network at speed, developing the Advanced Passenger Train

The Advanced Passenger Train was an experimental tilting High Speed Train developed by British Rail during the 1970s and early 1980s....

. The APT-E (E for experimental) was powered by gas turbines and the APT-P (P for prototype) was electric. With no tilting the train was developed to break the British rail speed record. Tilting trains were not new and used passive tilt, however not common, and not widely implemented. The engineers decided that active tilt was the key to success to negotiate curves at much higher speeds.

The train was advanced in both name and nature. Not only did it actively tilt, it had hydro-dynamic brakes, was articulated, had lightweight bodies, and two power cars in the centre of the train. The latter was necessary because two power cars were deemed necessary for the proposed schedule, but the use of a "roof-line" to send the 25 kV supply along the train, and thus allow the power cars to be placed at the ends of the unit, was not acceptable at that time. When the prototypes were built, worked and proven the engineering development team was disbanded and the trains handed over to British Rail's in-house engineering department to build. The pioneering developing engineers moved to different fields while British Rail engineered the train into a production model. The British Rail engineers, who had little to no involvement in the development of the train, changed some of the prime and proven engineering aspects. Such as, changing the active tilt mechanism to air rather than the developed and proven hydraulics.

The trains were introduced in 1981 and immediately taken out of service. During initial tests some passengers complained of being nauseous due to the tilting motion. Subsequently it was learned that this could be prevented by reducing the tilt slightly, so that there was still some sensation of cornering. The APT-P trains were quietly reintroduced into service in mid-1984 and ran regularly for a year, the teething problems having been corrected. The political and managerial will to continue the project and build in numbers the projected APT-S production vehicles, had evaporated under an in-house engineering management who felt slighted and by-passed in a project they did not develop. Despite being an eventual success, the project was scrapped by British Rail in 1985 more for political reasons than technical. This was another British innovation that was left to others to implement.

Some aspects of the technology were purchased by the Italian Pendolino

 group to enlarge its portfolio. Ironically, Pendolino export active tilting trains to the UK, the country that invented the active tilting train.

However, much of the technology developed for the power cars was subsequently used in the InterCity225 Class 91 locomotives, which run on the East Coast route from London to Leeds and Edinburgh.

). Class 403 was able to tilt 4°, but the fixed pantographs limited this to 2°. Shortly after the train had gone into service the tilting technology was disabled as many passengers experienced motion sickness because the pivotal point was too low.

 units for fast regional traffic. This time the results were quite satisfying and allowed a significant reduction of running times. Class 610 was followed by class 611 which basically was built for the same purpose (fast regional traffic with up to 160 km/h on twisting non-electrified lines). Class 611's tilting system was electric, with a maximum 8° tilt, based on military technology from the Leopard tank. However, after coming into service in 1996 this 50-unit class experienced problems both with the newly-developed tilting system as well as chassis and axles, so it was judged not successful. The tilting system was out of service until 2006, when hardened axles and system updates finally solved the problems. In consideration of these problems DB ordered a full re-engineering, resulting in the development of class 612

 an electric high-speed tilting train was commissioned. While classes 401 to 403 (without tilting technology) were to cover the newly built or modernized high speed lines at up to 300 km/h (class 403), classes 411 and 415 with maximum speed of 230 km/h were designed for older twisting main lines. A total of 60 class 411 and 11 class 415 (shorter version) have been built so far. Both classes worked reliably until late 2008 when cracks were found on an axle during a routine check. The tilting mechanism has been switched off since 23. October 2008 and the maintenance intervals were drastically reduced which lead to major service disruptions.

 was supposed to overcome this problem by using gyroscopes at the ends of the train and a master/slave control system which defined a "tilting curve" for the whole train. It would appear that the technology of the era was not able to implement this technique as well as required.

Modern tilting trains are profiting from state-of-the-art signal processing which senses the line ahead and is able to predict optimal control signals for the individual carriages. Complaints about nausea have by and large become a thing of the past.
