Indigenous bullet train B28 undergoes 'squeeze test'

In short

Safety assessments at the Bengaluru manufacturing plant confirmed the passenger compartment's ability to resist extreme pressures without suffering catastrophic deformation. BEML is currently building the initial pair of eight-coach trainsets, which feature an operational design speed of 249 kmph and test capability up to 275 kmph. Officials project the first physical prototype will finish assembly in under six months, preparing the train for scheduled performance trials on the high-speed corridor by mid-2027.

NEW DELHI: New Delhi: The country’s first indigenous high-speed train, B28, has undergone the vehicle body shell test, also known as the “squeeze test”, an important safety assessment to determine whether a train’s car body can withstand heavy external forces and pressure without excessive deformation or structural failure in case of a collision or crash.

The test was conducted at BEML’s production facility in Bengaluru. The central PSU is manufacturing the first two of indigenous bullet trains, each comprising eight coaches. The trains have been designed for an operating speed of 249 kmph and a testing speed of 275 kmph, as per a BEML tender document.

People aware of the development said the squeeze test is crucial as the trains will operate at high speeds and their car bodies must be capable of withstanding heavy forces in the event of a collision or accident.

“After the successful completion of this test, the prototype should ideally be ready in less than six months. Since the B28 (Bharat 28) train is not being built on Japanese Shinkansen technology, the development process should…
