• Few facts
Elisabeth Line is the brand name of Crossrail project
A fleet of 70 new 200 metre long trains built by Bombardier Transportation
in Derby will run on the Elizabeth line, each train will be able to carry up to
1,500 people.
The new, high-capacity trains have:•Seven fully interconnected, walk-through carriages (converted to nine carriages
when the Elizabeth line fully opens)
•Air conditioning and real-time information on-train
•Information on next stops for passengers•Energy-efficient management systems including regenerative braking which
uses up to 30% less energy
•Capable of running up to 90 mph on outer sections

• This screenshot shows an extract of electrical schematics showing interface between CBTC and ETCS as well as the interfaces shared or not shared with the Cl345 vehicle. CBTC is managed as STM by ETCS.
• Signalling engineer contributes or create these schematics. Usually, a more senior Vehicle Architecture engineer has ownership of the electrical schematics.
• This ETCS-CBTC hardware wiring allows seamless level transitions between CBTC and ETCS and vice-versa. Software will command and control as well!
