Israel - Rolling stock

Description

NTA have issued an RFI in relation to innovative solutions for future-ready rolling stock, including energy efficiency, optimised performance, material, maintenance and more, from suppliers which have proven experience with rolling stock design and production for metro systems.

Section 3 gives a high-level overview of the technical specifications of the metro trains:

• the train power supply voltage system shall be 1500V dc

• the operating height of the pantograph shall be coordinated with the ROCS as well as FOCS

• the signalling system is GoA4, hence the Rolling Stock needs to be compliant with the grade of automation of the signalling system

• the trains shall be designed for the nominal track gauge of 1.435 mm

• the train design speed shall be 90 km/h and the operating speed shall be 80 km/h

• the train design shall limit the longitudinal jerk to 0.75 m/s3

• the train electro-dynamic brake fade-out shall not occur above 3 km/h

• the maximum acceleration shall be limited to 1.3 m/s² at an adhesion limit (motoring) of 18%

• the maximum service brake deceleration shall be limited to 1.2 m/s²

• the maximum emergency brake deceleration shall be limited to 1.3 m/s²

• the train design shall be able to accommodate minimal track radius of 100 m in depot and 250 m on the line. The rolling stock design shall be capable of running normally under all operational conditions at the maximum gradient

• all trains shall be bi-directional with doors on both sides

• the train design shall comply with the international and local applicable codes and standards for electromagnetic interference and compatibility (EMI/EMC)

• the train design shall ensure that the noise levels and measuring are in accordance with compliance stated in ISO 3095 and ISO 3381

• each trains shall ensure passenger running comfort according to EN 12299

• trains shall be equipped, with an onboard derailment detector system with at least SIL level 3

• the frame design shall result from finite element analysis (FEA) and validated by means of specific structural tests

• the minimum transportation capacities of the rolling stock of the lines shall consider 4 passengers per square meter and 20% comfort ratio

• the car body shall be designed and validated in accordance to UIC 566/EN 12663 Category P-III and EN 15227

• the bogie system shall be of proven design and technology in compliance with international standards

• bogie frame service life shall be over 30 years

The deadline for the RFI is 22 May 2025.
