Speed of the Mayan Train Tests Generates Doubts

The supervision of the Mayan Train concluded successfully, but the speed of the Mayan Train tests generates doubts. Experts help us clarify these unknowns.

The Mayan Train, one of the most controversial but also emblematic initiatives of President Andrés Manuel López Obrador’s mandate, has been the subject of multiple criticisms.

Despite the controversy, the project’s preliminary operational tests began on September 1 and 2, 2023, in a phase that has not yet completed its infrastructure in the planned 1,500 kilometers.

During these first tests, various authorities were present, including the president of the nation, the governor of Yucatán, Mauricio Vila Dosal, and the governor of Quintana Roo, Mara Lezama.

However, something that caught attention was the speed at which the tests were carried out: 30 kilometers per hour, significantly less than the promised 160 kilometers per hour, according to the official portal of the Government of Mexico.

Speed of the Mayan Train Tests Generates Doubts

Daniel Rodríguez, an industrial designer with experience in railways, explains that testing for a train is generally divided into two key stages: train certification tests and interface tests that evaluate the relationship between the train and the infrastructure.

A train is a sophisticated mechanical entity that needs to go through a battery of rigorous tests,
points out Rodríguez.

Focus on Train Certification

Before the train can operate at commercial speeds, it is crucial to determine appropriate distances for acceleration and braking on various segments of the line.

During this stage, repeated tests are carried out on representative sections at reduced speeds to evaluate the train’s response and verify vital systems such as the engine and batteries.

Additionally, structural analyzes are performed and sensors and computers are placed on the train to monitor performance.

Interface Evaluation

These tests are particularly critical when both the train and the infrastructure are new. An ‘envelope boundary’ is used to ensure that there are no obstacles on the track that could interfere with the train.

In addition, the transmission of signals through antennas is verified to ensure that the train meets the speed and safety distance requirements.

Although the speed of the Mayan Train’s initial testing has raised some concerns, this cautious approach is part of a rigorous process designed to ensure the long-term safety and effectiveness of the system.

Additionally, drivers are trained under the supervision of experts, which includes familiarization with train systems, operation and maintenance protocols, and emergency procedures.
