THE FOLLOWING SPECIFICATION PARTICULARLY DESCRIBES THE INVENTION AND THE MANNER IN WHICH IT IS TO BE PERFORMED.

Field of the Invention:
This invention relates to railways.
In particular, this invention relates to traffic control for railways.
Still particularly, this invention relates to a simulator for simulating traffic scenarios and control for railways at a station.
Background of the Invention:
Railways form an essential way of terrestrial transport. Its safety and its efficiency is enabled by its management. Running a multitude of trains on a system requires appropriate planning, monitoring, and executing of tasks within the specified guidelines. Signaling is of prime importance in such a system to ensure its safety. Designing of a robust signaling system and providing the means to monitor it ensures its stability.
Railway signaling is a system used on railways to control traffic safely, for example, to prevent trains from colliding. Trains are uniquely susceptible to collision because, running on fixed rails, they are not capable of avoiding a collision by steering away, as can a road vehicle; furthermore, trains cannot decelerate rapidly, and are frequently operating at speeds where by the time the driver/engineer can see an obstacle, the train cannot stop in time to avoid colliding with it.
When trains are operating in opposing directions on a single-line railroad, meets are scheduled, where each train must wait for the other at a point they can pass. Neither is permitted to move until the other has arrived. If two

trains cannot be running on the same section of track at the same time, then they cannot collide. So railway lines are divided into sections known as block sections, and only one train is normally allowed in each block section at one time. This principle forms the basis of most railway safety systems.
A set of General and Subsidiary Rules (G. & S. R.) in India provide the framework for safe train operation and are followed strictly. To ensure safe reception and dispatch of trains in compliance with G. & S. R. at every station, a panel instrument is in place. This, in combination with block instruments serves the above purpose. Hence an important portion of training of station masters is training on operations of panel and block instruments.
Training modules are relegated to on-the-job sessions. This limits the variety of the nature of problems and scenarios occurring. A trainee without the instructor is confined by the various rules and procedures within which he can operate and learn. With the instructor, the practical know-how is limited to the variety of conditions actually occurring with respect to the surrounding parameters. Hence, it is difficult to train the trainee for complex situations which may have never occurred but have a reasonable chance of occurring.
The hard-version of a signaling system encompasses a complete working panel, up and down block instruments, and a variety of counters.
In Indian Railways, station masters operate a Block Instrument (BI) for obtaining line clear and dispatching a train into the block section under a

system of working called Absolute Block System. In this system of working, it is ensured that a block section (usually a section between two stations) is occupied by only one train in a given moment. This is to ensure that there is no head-on collision or rear-end collision of two trains moving on the same track. For a single line system "Non-Co-operative Tokenless Push Button" block instrument of Podanur type is typically used. For a double line section "SGE Lock and Block" block instrument is typically used. In combination with signaling circuits of the station and block instrument of the adjacent station, the block instrument ensures that a train can be let into a block section only if it satisfied the rules of the Absolute Block System.
The Station Master operates a panel for reception, dispatch, and movement/placement of trains in various running lines of the station. This could either be a "Panel Interlocked" (PI) system or a "Route Relay Interlocked" (RRI) system. In the former system (PI), all points which are used to switch the train from one track to another are first operated independently. Then the governing signals are taken off to set a "route". In the latter system (RRI), the panel enables operation of points and the governing signals in one single operation. Both the above systems are governed by logic which prevents setting conflicting paths within a station that could cause collision between two trains moving in either the same or opposite directions. This logic is contained in a "Selection Table" which is a matrix of all signals, route and point settings. Besides physical infringement and collision, the logic also accounts for "adequate distance" beyond stop signals to buffer against overshooting a signal. This is implemented in the field by a complex and elaborate set-up of points, circuits and relays.

Typically, over a three line station, 15 track circuits and 250 relays are involved.
Conventional method of training includes training directly on such consoles. In a real time panel, a sequence of buttons are used in order to confirm an action to be taken. This sequence of buttons eliminates accidental key presses, and non-confirmed actions are thus eliminated. There is a need for a simulator that simulates the exact working of the panel and block instrument, and provides the same experience.

In accordance with this invention, the control means is simulated to map the exact functions of the original keyboard wherein a multiplicity of key

strokes are required to enable an action. In a hardwired board controlling actual train signals, this feature is enabled. The same feature is now incorporated as a part of this simulator system for precision training of the trainees learning to be station masters and be adept at controlling the traffic movement. According to this invention, there is an incorporation of a physical panel with buttons similar to the actual panel (instead of input operations through mouse clicks) for a real feel. Also, simultaneous pressing of buttons is implemented exactly as in a real life scenario as against double click of a button on the screen followed by single click on another button as implemented in the simulators of the prior art. A microcontroller has been used to interpret the input, which is then fed to the main application means. Thus, the trainee is exposed to complex schemes of functioning, by nature of the scenarios presented to him, as well as by the nature of control mechanisms provided to him, thus aiding him/her to multitask, and be aware of all scenarios; either in normal mode or in emergency mode.
Typically, there is provided a viewing means adapted to provide a view of the exact present state of a signal by using a function of the controlling means. This is not available to a station master in conventional training on panel.
According to another exemplary embodiment of the system of this invention, controller means may be adapted to include the following mechanism and procedures:
- Locking Mechanisms:

- Approach Locking Mechanism: This is provided to prevent the
signal from being taken off when it is put back to danger in face of an approaching train and to prevent the route being altered.
- Dead Approach Locking Mechanism: If a sufficient length of track
circuit is not provided in rear of a signal like home signal, starter signal (from goods' yard) and shunt signal (from sidings), approach locking is not provided. In such cases, another type of approach locking is adopted called Dead Approach Locking. It becomes effective on the put back of signal and does not depend on approach of train.
- Cancellation Mechanism:
- 3 Button Cancellation Mechanism: The three button cancellation
releases or normalizes all the route sections as well as the overlap if set at the same time. The locking becomes free soon after the 3 button panel operation for route release, if track circuits in approach of signal are not occupied, nor failed and the signal is at ON position. If they are occupied, the route release takes place after a pre-determined time delay.
- Emergency Cancellation Mechanism: This is required when one
needs to cancel the route which is set and cannot be cancelled using 3 button cancellation mechanism. There is a need for the signal inspector to be present and the signal inspector's key to be inserted into the slot.
- Route Indicating Mechanism: It indicates a signal to the driver for indicating the appropriate route on which the train is being received,
- Visual Indicating Mechanism: These are the signaling aspects. Typical examples of this can be red signal for dead stop, single yellow

signal for proceeding with caution and being prepared to stop at the next stop signal, double yellow signal for proceeding with attention and being prepared to pass next stop signal at restricted speed, green signal for proceeding, and the like signals. - Sensing Mechanism: adapted to sense the presence of a vehicle on a portion of a track, whether the track is occupied or not, and the like.
In accordance with yet another version of the system for simulating control of signals within a railway, there is provided a network of computers; one for each station, to represent adjacent stations and the main station for implementing line clear and dispatch/reception operations between these computers. This system supplements/replaces a traditional room model.
Typically, this system is adapted for a single line version. Alternatively, this system is adapted for a double line version.
Any number of computers over a network can now be connected to simulate a route of stations. Granting of line clear, dispatch, reception, and the like is provided by means of controlling means. Typically, a physical panel and block instrument with buttons as controlling means is designed similar to the actual panel and block instrument. This gives a realistic feel to the trainees.

Detailed Description of the Accompanying Drawings:
Figure 1 of the accompanying drawings illustrates a system for simulating control of signals within a railway network. It comprises a simulation means (SIM) which includes a first memory bank means (FMB) adapted to store mapped information with respect to track profiles, station profiles and signal profiles within said network, a second memory bank means (SMB) adapted to store train movement data within said network, a selection means

(SLNM) adapted to select a pre-determined area within said network. The system further includes a visual representation means (VRM) adapted to show track profile, station profile, and signal profile of a selected area within said network, a processing means (PC) adapted to fabricate envisioned or plausible situations of train movement within said network, a controlling means (M/KB) adapted to virtually control and respond to a plurality of virtual representations of train movement within said network, and a result calculating means (RCM) adapted to correlate inputs from said controlling means with a pre-defined result of the simulated control.
Figure 2 of the accompanying drawings illustrates the simulation means (SIM) in accordance with this invention along with the input-output consoles and features. The Train Movement block (TM) in conjunction with the database (DB) of events generates a plurality of events; either normal (N) or abnormal (AN) in nature. The various route scenarios (R) and manual triggers (TG) provide a variety of arbitrary datasets for learning. These input parameters are simulated in the simulation block (SIM) and provide the end-user i.e. the trainee (SM) various kinds of outputs upon which he can act.
Figure 3 illustrates the Result Calculating Means (RCM) in conjunction with the simulator means (SIM). The Result Calculating Means (RCM) receives and records all actions in relation to a trainee. It has a data reference means adapted to store true responses of archived real-time events (RD) and the true responses of any unique scenario or response method in a new data bank (ND). A trainee's (SM) responses are compared with the stored responses (RD, ND) with respect to static and dynamic parameters and in response to previous training sessions. This provides a better qualitative and quantitative

analysis for a trainee. It further includes a first calculating means (FCM) adapted to calculate a score for said simulated controls with respect to said correct referenced responses, and a second calculating means (SCM) adapted to measure the response time taken for user to react to said virtual representations.
Figure 4 illustrates a schematic of the system of this invention. A central core (10) is present which represents the panel for providing simulations and controls. Typically, a physical panel (20), with buttons, and physical block instruments (30, 40) with controlling means (140) is designed similar to the actual panel and block instrument. The controlling means (140) is adapted to recognise a plurality of keystrokes (i.e. simultaneous pressing of buttons of a controlling means), by means of input interpretation means (150), for a command to be effected, and preparing the trainee for real life situations. This gives a realistic feel to the trainees. Adjacent stations having separate cores (50, 60) are provided and connected to said central core (10) via a networking means. Various databases such as a scenario database (70) adapted to prepare various permutations and combinations of simulated scenarios, a training database (80) adapted to provide training modules and tests, an object state database (90), a signaling table database (100) adapted for providing signaling mechanisms in relation to said scenario database (70), are provided. A screen (110) for viewing simulated movement of train, and an audio means (120) for providing aural feeds of alarms or signals is provided. The hardware (130) refers to the microcontroller.
