1. A method comprising:
obtaining, by a display computing system, a first data series of measured speed records and a second data series of predicted speed records at a visualization time during travel of a train, wherein:
the measured speed records indicate measured speeds of the train over a measured span trailing the train in a direction of travel,
the predicted speed records indicate predicted speeds of the train over a predicted span ahead of the train in the direction of travel, and
the predicted speeds are determined by computing the measured speeds as inputs to a prediction model;
determining an output interface length for the train based on a predetermined threshold length on an output interface of the display computing system;
determining a position for a visualization of the train on the output interface based on the output interface length; and
rendering, on a visualized space of the output interface in communication with the display computing system, a measured speed trend comprising:
the measured speeds in a first region of a track topology comprising the position of the visualization of the train and a trailing distance; and
a predicted speed trend comprising the predicted speeds in a second region of the track topology.
