Key Event Details
Kalyani Cast Tech Limited received a letter dated 26 October 2026 from RDSO (File No. RDSO-MW0PWDA(CNTR)/1/2025-O/o PED/SW/RDSO) granting Stage-I Concept Design Approval for the company's proposed new wagon design for carrying ISO/domestic/dwarf containers under the Procedure for New Wagon Design Approval (PWDA) Scheme.
Approval Specifics
The approval covers Diagram drawing numbers:
- KCTL25-A-01 (A-Car)
- KCTL25-B-01 (B-Car)
- KCTL25-C-01 (C-Car)
The approval is granted subject to compliance with stipulated conditions relating to the negotiability of the proposed new design wagons over:
- Simple curves of 10 degrees
- Two closely located (SRJ to SRJ distance between 0 m to 5m) 1 in 8.5 turnouts of 2nd and subsequent loops
Next Steps Required
The company must submit requisite documents for Stage-II ('5.2 Detail Design Approval') as per PWDA policy no. WD-02-WDA-2009, incorporating the following:
1. Modifications and updates in Guard container design in line with revised wagon design parameters, incorporating Locking, bolting and fixing arrangement
2. Detailed Dynamics simulation reports as per para 5.2.2 of PWDA policy, which must include:
- Simulation establishing that proposed rolling stock combinations (A & C cars, C & B cars, and C & C cars) can negotiate two closely spaced 1 in 8.5 turnouts in 2nd and subsequent loops with SRJ-to-SRJ distance from 0 m to 5 m
- Simulation reports indicating proposed rolling stock can negotiate 10 degree simple curve
Correspondence History
The approval follows previous correspondence:
- RDSO letter dated 24.07.2026
- Company letters dated 31.08.2026/02.09.2026 (in response to RDSO observations)
- Company letter dated 21.09.2026
Business Implications
The approval marks an important milestone for the company and is expected to support its efforts to expand its presence in the railway wagon segment and explore potential business opportunities in container transportation.
