In one embodiment, a method includes receiving first Light Detection and Ranging (LiDAR) data associated with a railroad environment, extracting an asset from the first LiDAR data associated with the railroad environment, and superimposing the asset into a spatial model. The method also includes receiving a field indication associated with a modification to the railroad environment and modifying the spatial model in response to receiving the field indication associated with the modification to the railroad environment. The method further includes receiving second LiDAR data associated with the railroad environment and comparing the second LiDAR data to the modified spatial model.

A train simulator test set is disclosed that can be operably coupled to a railroad track to measure the resting impedance of that track circuit and simulate a train by varying the railroad track inductance over a set period of time. The test set can select the speed, direction, and number of trains to simulate. By applying a variable inductance on the railroad tracks, the test set can simulate a train moving at variable speeds toward and away from the island. The test set can apply inductances to the railroad tracks to simulate two or more trains moving in each direction of the tracks at the same time, along with multiple looks and routes. The train simulator test set can include simulation software to vary the parameters of the train simulation and couple a variable inductance on the railroad tracks.

An object of the present invention is to improve the image quality of images obtained during travelling even in inferior environmental conditions. A camera 101-1 is mounted in a train 1-1, and a camera 101-2 is mounted in a train 1-2. Each of the camera 101-1 and the camera 101-2 images the same physical object at different times while moving along the same track 5. A processing apparatus 2 generates a synthetic image 7 by synthesizing images related to the same physical object imaged by the cameras 101-1 and 101-2 while moving along the same track 5, and displays the same on a display screen 2A.

A method and an apparatus for a train control installation are disclosed, and are based on the absolute permissive block concept. The train control installation employs a plurality of generic absolute block signal units (ABSU), wherein each signal unit includes means for detecting the crossing of a train passed a discrete point, means for exchanging data with adjacent ABSUs, means for generating and communicating a movement authority limit to a train, means for generating and displaying a signal indication, and means for enforcing a stop aspect. The train control installation can be used in conjunction with a communication based train control (CBTC) system to provide a degraded mode of operation without impacting the availability and the reliability of the CBTC system. Further, the train control installation has a self-healing feature to maintain train service during an ABSU failure.
