What is an extra train?

An extra train is defined as a train that is not specified in the operating schedule or bulletin. This classification allows railways to add trains as necessary to accommodate additional demand or operational needs without altering the standard schedule. Extra trains can be arranged to handle increased passenger traffic, accommodate freight loads, or respond to unexpected situations such as delays or service interruptions.

In contrast, trains that operate with a normal schedule are part of the established timetable and do not fall under the category of extra trains. The same applies to a passenger train on a schedule during peak hours, which is simply an adaptation of regular service, and a freight train designated for special routes, as those always adhere to defined transport parameters. The flexibility afforded by designating a train as "extra" is essential for efficient rail operations and management.
