The BEML B28 (also known as Train B28 or Vande Bharat 250) is India's first indigenous high-speed trainset, developed by BEML Limited. It is designed for an operational speed of 250 km/h and a structural design speed of 280 km/h.

Development

In October 2024, the Integral Coach Factory (ICF) awarded a strategic contract worth ₹866.87 crore to BEML. According to U.R. Subba Rao (Director, BEML), the project transitioned to active manufacturing in early 2026 at the Bengaluru complex. The first prototype is expected to roll out by late 2026.

Shantanu Roy (CMD, BEML) described the B28 as a "strategic technology milestone" involving advanced Train Control Management Systems (TCMS).

Route & Operations

Primary Corridor: Mumbai–Ahmedabad High-Speed Rail.
Trial Stretch: Surat–Bilimora section starting late 2026.
Commercial Launch: Expected by August 2027.

Technical Specifications & Design

AerodynamicsLong-nose design (Shinkansen-style) to reduce tunnel piston effect.

CarbodyAustenitic stainless steel with high-precision welding.

BogiesBolsterless high-speed bogies with advanced damping.

PropulsionMedha Servo Drives (Distributed Traction).

Interior & Water Management

Verified through DGCI&S tenders, the B28 includes:

Executive Class: 180-degree rotating seats and enhanced legroom.
Climate Control: Pressurized HVAC units by Knorr-Bremse (Merak).
Sanitation: Pressurized modular toilets designed for speeds of 250 km/h and temperatures from -5°C to 50°C.
Accessibility: Special provisions for PRM (Persons with Restricted Mobility).

Safety & Engineering

Evacuation: Specialized "Ladders-cum-bridge" systems for emergency egress.
Crashworthiness: Energy-absorbing elements in the driving cab structure.
Visibility: Reinforced wrap-around glass for high-pressure tunnel transits.
