Abstract
A conventional railway system usually has several train types with various services operating on the same line. Difference in train characteristics leads to different capacity impact to the system. Rail line capacity is commonly defined as the maximum number of trains that can be operated on a section of a track with an expected level of service within a given time period. However, a particular unit (trains/hour or trains/day) does not reflect the train type the unit refers to. Since different trains do have different characteristics, it is essential to develop a method to convert different types of trains into a standardized unit. In this study, a new concept is proposed, namely, the base train equivalent (BTE), along with a standardization process to classify different train types in accordance with the particular type defined by the user. This concept is similar to the passenger car equivalent (PCE), which converts trucks to passenger car units in classifying highway transportation. BTE is used to convert the trains on the line into a base type of train based on the results obtained from capacity analysis. I developed several methods to determine BTE according to specific types of capacity analysis, such as analytical, parametric, and simulation capacity models. Using the proposed method, capacity measurements from different lines or systems can be compared and evaluated, resulting in meaningful and useful attributes.
