PACT TechnologyPACT is a collection of many new and innovative technologies along with some pre-existing ones. We have modified these pre-existing technologies to fit them into our Project PACT.
Some of the main technologies behind PACT have been described below- Magnetic LevitationMagnetic Levitation is a system of transportation that suspends, guides and propels vehicles, predominantly trains, using magnetic levitation from a very large number of magnets for lift and propulsion. This method has the potential to be faster, quieter and smoother than wheeled mass transit systems.
Changing Of Tracks/Switching of tracksPre-existing rail networks use the technology of movement of tracks to change the path of the train.
Unlike this, PACT has another new special technology (not named yet) which enables the cart or pallet to switch tracks without the movement of tracks. This is the most complicated technology in the entire system of PACT There are two moving panels on the front side of cart. These two panels are the ones responsible for switching of tracks. These panels are located on the opposite side of the surface of track attached to the cart's front part. Suppose the cart has to switch over to a track that goes towards right instead of moving straight. The panels on the front part of cart shift toward right few seconds before the cart turns. Now these panels get locked from the right side while the left side remains free. The lock made by the panels aligns the cart to the track toward the right while the track going straigh is now free. Getting aligned to the right track, now the cart can leave the straight track. The breaks between the tracks allows the other part of cart (instead of the panels which are now bound to move right) to leave the initial track and move to the right track. Now the time comes when the cart makes turn and leaves the initial track to move onto another track. This way cart switches track without letting the track move. The slide show below shows a series of pictures to make it clear how a cart changes or switches tracks. All of this is done within seconds without the need of the cart to be stopped.

TurningSometimes PACT needs to take some sharp turns along the pathway. Pact overcomes this problem by using another turning technology which enables cart to make a turn at very short radii. The front and rear part of the cart moves independently along the path. Each of then are connected independently to a plane surface with an axle. The axle allows them to freely rotate along the plane surface. This plane surface carries the vehicle over it. The technology has been illustrated graphically below-
LocksThe plane surface of the cart has some inbuilt outcomings called locks. These locks help the vehicles to stay still while the carts transport them to their required destination. To use the PACT every vehicle has to make a small modification of adding a space where the locks can attach themselves to the vehicle.
SpeedThe speed of every cart on Pact track remains the same while it reduces when making turns. A uniform speed is maintained on straight paths while no vehicle is allowed to stop on the main carriageway. There is always a fixed distance maintained between carts ensuring safety.
