The Train Energy Model (TEM) developed under the AAR's Energy Program is a train performance simulator used to predict fuel consumption for any train on any route. As with all simulation models, TEM must be "validated" so that users in the railroad industry can have confidence in the results obtained with TEM. To achieve this objective, two revenue service tests were conducted using two types of trains: a unit coal train and a mixed intermodal train. This article presents a summary of TEM validation efforts.
The train operation and performance in TEM is governed by the Automatic Train Handling Algorithm (ATA). ATA is a form of "artificial intelligence" that seeks ...
