SYSTEM AND METHOD FOR SCORING TRAIN RUNS
A train control system uses sensory inputs related to operational parameters of a train for automatically scoring or classifying particular train driving strategies implemented by a machine learning model for a particular train operating on a predefined route or route segment. The train control system includes one or more predefined rules related to one or more of a first set of the operational parameters, wherein each of the rules defines a Boolean, true or false classification based on whether a particular train driving strategy results in one or more of the first set of operational parameters complying with the rule. One or more comparative key performance indicators are related to one or more of a second set of operational parameters, and are used to rank the particular train driving strategy for the predefined route or route segment relative to a different train driving strategy for the same or comparable route or route segment.
QUASI-MOVING BLOCK SYSTEM OF TRAIN CONTROL
A system of train control uses a quasi-moving block methodology for controlling operation of a plurality of trains from a remote office. The office parses the route information for each train into non-overlapping movement authorities that are issued via a communications network. As each train proceeds, it communicates with the office to automatically roll up its movement authority and release the portion of the movement authority behind the train. The office then extends the movement authority of the subsequent train to reflect the released portion of the movement authority of the leading train. The track can be divided into a series of track circuits to enable detection of broken rail or unexpected occupancy. The office segment can then control operation of trains accordingly if broken rail or unexpected occupancy is detected in the train's movement authority.

Micro sleep for network node providing service to user equipment onboard a high speed train
In one aspect, a network node receives a message indicating that UEs that require service are expected to enter a service area of the network node. The network node determines, based on the message, that a change in power management for radio equipment corresponding to the service area is required. The network node determines a timing for initiating the change in power management for the radio equipment, taking into account a predicted time for when the UEs are expected to enter the service area, and triggers the change in power management for the radio equipment, based on the determined timing. In another aspect, the network node predicts a departure time from the first service area for the UEs. The network node then sends to another network node, prior to the predicted departure time, an indication that the UEs are expected to enter a service area of the other network node.
