The Diesel Hydraulic Multiple Unit (DHMU) train set successfully finished its trial run on the Kalka-Shimla heritage track on Sunday, May 24, 2026. The train started from Kalka at 9:17 AM and reached Shimla at 2:44 PM while carrying a 5.1-ton load. This run focused on fixing technical issues and improving passenger facilities.
What were the key highlights of the trial run?
The trial was conducted to check the engine temperature, braking system, and overall passenger comfort. The Integral Coach Factory (ICF) Chennai worked on fixing the cooling system to prevent overheating, which was a problem in earlier tests. The Ambala Division of Northern Railway managed the route to ensure everything worked smoothly.
What are the new features of the DHMU coaches?
- Each bogie has control panels that sound an alarm if a technical fault occurs.
- The system points out the exact problematic section, so staff do not need to check the whole train.
- New coaches aim to increase speed and reduce travel time by 45 to 60 minutes.
- Modern facilities are added to make the heritage journey more comfortable.
What is the next step for passenger operations?
This was the final summer trial for the DHMU. A detailed report will now be sent to the Commissioner of Railway Safety (CRS). Once the CRS conducts the final test and gives the certification, the train will be officially cleared for passengers. Additionally, a new Vistadome train rake was commissioned for this route in January 2025.
