The present disclosure relates generally to a simulation of locomotive enforcement events including penalty, emergency, and horn, and more specifically to systems and methods for simulating physical and electrical characteristics corresponding to Positive Train Control enforcement events.
Positive Train Control (PTC) systems use communication-based and processor-based train control technology to reliably and functionally prevent train-to-train collisions, over-speed derailments, incursions into established work zones, and movements of trains through switches left in the wrong position. PTC systems harmonize interoperability between electrical and mechanical systems to act in moments when a locomotive disregards a safety plan. For example, the PTC system operates in response to identifying speed of the locomotive is greater than the route speed allows enabling a penalty to the locomotive by applying the brakes. The Federal Railroad Administration mandates PTC systems operating on every mile of railroad meaning every locomotive on the railroad includes a PTC system.
Teaching how a PTC system operates on a locomotive currently lacks any ability to simulate the system components. While training on a locomotive with the PTC system is ideal, this is unlikely because of the inability for a trainer to obtain the locomotive for the time to properly train the upcoming engineers and conductors. Training engineers and conductors can take weeks, months, even years, so removing a locomotive from use can create dissatisfactory efficiency. Additionally, because trainees focusing on becoming an engineer or a conductor cannot practice in a practical environment, the trainees receive insufficient training. Engineers and conductors without proper training with the PTC system can frequently trigger the PTC system on the locomotive by traveling with unsafe locomotive handling. While the PTC system ensures for enhanced safety the risk continues for train derailments and train-to-train collisions.
The present disclosure achieves technical advantages as a system and method for simulating PTC systems in a local environment using software and hardware, removing the training program from using an actual locomotive. The system can simulate various functionalities of the PTC system in a classroom environment using software and hardware components. For example, the system can couple the software of a train management computer (TMC) to electromechanical valves to simulate air compression on brake pipes in response to the PTC system executing a penalty on the locomotive. The system can display statuses of various systems on the locomotive to a user using a cab display unit (CDU). For example, the TMC enables the hardware and software of the system to communicate information relevant to analyzing warnings from the PTC system. The system can control the software and hardware components to simulate warnings and actions from the PTC system allowing trainees to experience the PTC system for optimum training.
The present disclosure solves the technological problems of providing insufficient training for interacting with the PTC system and restricting trainees from experiencing the PTC system in action by simulating warnings and actions from the PTC system using stand-alone system components, which removes the locomotive from at least some of the training program. By removing the locomotive from at least some of the training program yields flexibility to the instructors while optimizing education for the trainees. Additionally, removing the locomotive from some of the training saves time for the training program while enabling immediate feedback to handling the locomotive in response to the PTC system warnings. Separating at least the initial PTC training for the novice engineers and conductors from operating on locomotives also minimizes liability and risk, such as breaking components on the locomotive and potentially causing a hazardous safety environment.
The present disclosure provides a technical solution to the technical problem by providing software and hardware components for instructional purposes. Particularly, the present disclosure focuses on optimizing training conditions for interacting with the PTC system. In a real-world environment, the PTC system can transmit warnings and instructions to the locomotive instructing it how to respond to certain situations. The present disclosure provides control mechanisms interacting between software and hardware components to simulate a locomotive environment. The simulated locomotive environment enables a user to practice interacting with the PTC system without physical repercussions, such as the PTC system applying the brakes to the locomotive. The present disclosure enables users to interact with locomotive components in a system coupling components corresponding to the PTC system in a classroom environment.

In another example, the switches can include a relay which can include a switch that is operated by another electrical circuit.
The terminal board(s) 114 can include an insulating slab on which electronic terminals are mounted. For example, the terminal board(s) 114 can include one of various materials commonly used as the insulating slab. In an example, the insulating slab can include materials such as polyester, teflon, silicon wafer, among other insulating materials. In another example, the electronic terminals can include inputs or outputs from various electronic components used in the simulation system 100. In an example, the inputs and outputs can include copper terminals from switches, relays, or some other electronic component. In another example, the terminal board(s) 114 can provide an interface between the TMC 110 and the pneumatic air assembly 116. For example, the terminal board(s) 114 are physically coupled to each of the switch box 112 and the air pneumatic assembly 116 using a conductive material. In another example, the terminal board(s) 114 can route a plurality of inputs from the switch box 112 as outputs to the pneumatic air assembly 116 based on a circuit schematic of the simulation system 100. For example, the switch box 112 can transmit the output from a penalty cutout switch of the switch box 112 to the terminal board(s) 114, and in turn, the terminal board(s) 114 can transmit the output from the penalty cutout switch to the corresponding component in the air pneumatic assembly 116.
The pneumatic air assembly 116 can receive an electrical input and convert the electrical input to mechanical energy to control air pressure. In an example, the pneumatic air assembly 116 can include at least three systems. For example, the at least three systems can include a penalty assembly 118, an emergency assembly 120, and a horn assembly 122. In an example, the pneumatic air assembly 116 can interconnect the components of the at least three systems using a combination of electrical and electromechanical components. For example, the inputs to the pneumatic air assembly 116 can include conductive wire or cable to transmit various electrical signals representing information from the terminal board(s) 114.

For example, a magnetic valve can use magnetic actuation to enhance response time and improve stability positioning.
The penalty assembly 118 can receive an electrical input and convert the electrical input to mechanical energy to control air pressure based on a penalty instruction from the TMC 110. For example, the penalty instruction from the TMC 110 can correspond to a trainee mishandling the simulation system 100. In an example, the trainee can mishandle components of the control stand 104 resulting in the TMC 110 to execute the penalty instruction, which in turn, results in the penalty assembly 118 receiving the penalty instruction. Alternatively, in another example, the penalty assembly 118 can include components energized at all times. For example, the penalty assembly 118 can include at least one magnetic valve in a state of being energized at all times, and when a voltage from the at least one magnetic valve decreases to a threshold, the penalty assembly 118 will be engaged.
The emergency assembly 120 can receive an electrical input and convert the electrical input to mechanical energy to control air pressure based on an emergency instruction from the TMC 110. For example, the emergency instruction from the TMC 110 can correspond to a trainee mishandling the simulation system 100. In an example, when the voltage of the magnetic valve in the penalty assembly 118 lowers, the drop in voltage instructs the emergency instruction to execute, which in turn, results in the emergency assembly 120 to be enabled. Alternatively, in another example, the emergency assembly 120 can include components in a low energy state at times other than when the magnetic valve of the penalty assembly 118 is in a low voltage state.
The horn assembly 122 can receive an electrical input and convert the electrical input to mechanical energy to control air pressure based on a horn instruction from the TMC 110. For example, the horn instruction from the TMC 110 can correspond to a trainee instructing the simulation system 100 to activate the horn of the locomotive. In an example, when the trainee executes the horn, the action by the trainee instructs the horn instruction to execute, which in turn, results in the horn assembly 122 to be enabled. Alternatively, in another example, the horn assembly 122 can include components in a low energy state at times other than when the trainee activates the horn.
The power supply 124 can include an electrical device that supplies electric power to an electrical load. For example, the power supply can convert electric current from a source to the correct voltage, current, and frequency to power a load. In an example, the load can include the various components of the simulation system 100. For example, the power supply 124 can distribute the proper voltages from an external bench power supply to generate the excitation for the functionality of the electrical aspect corresponding to the pneumatic air assembly 116, along with the components of the control stand 104. In another example, the bench power supply can include a 65 volt and 1.65 amp power supply. In an example, the proper voltages can include positive and negative voltages which are then transmitted to the various locations discussed above.
