"Blue Lotus" handrail

The train design of subway 1, 2, and 3 lines highlights humanization. According to the ergonomic design principle, the lotus handrail in the car is convenient for many passengers to use at different angles; The trains of Metro Line 2 and Line 3 not only inherited the humanized features of 1 train, but also installed lotus handrails, electric seats, air conditioning systems, pull-tab handrails, etc. The pull-tab handrail of Metro Line 2 is yellow, and the pull-tab handrail of Metro Line 3 is blue, which is also the most intuitive way to distinguish the interior of Metro 1, Line 2 and Line 3.

Electric heater with faster heat dissipation

There is a little difference in the installation position of electric heaters between metro lines 2 and 3 and metro line 1. An electric heater is installed under the carriage seat of the subway 1 line train, which will be turned on in time according to the change of external temperature to ensure passengers to be more comfortable when riding in winter. In addition, in order to provide passengers with a more comfortable riding environment, the air conditioning system in the car is turned on according to the change of external temperature to ensure passengers to be more comfortable when riding in summer. The electric heaters of metro lines 2 and 3 are not installed directly under the seats, but on the inner wall of the carriage, perpendicular to the seats, which prevents some passengers from stuffing garbage into the gap between the electric heaters and the seats and makes the carriage environment cleaner and more comfortable. "On the subway line 3 train, the way of directly heating the seat is cancelled, so that the generated heat is directly radiated into the carriage, and the heat dissipation speed will be faster than before." The staff told reporters.

Diagonal fire extinguisher

There are four fire extinguishers in each carriage of Metro Line 3, which are placed diagonally to facilitate passengers' access. The reporter saw that the fire extinguisher in the subway line 3 train was embedded in the inner wall of the carriage and covered with a transparent cover. When passengers find that the car is on fire, they can open the cover and take out the fire extinguisher to save themselves.

According to reports, the requirements for fire prevention, fire resistance, smoke prevention and gas protection of the materials and components used in the trains of Metro Line 3 have reached the corresponding foreign grade standards. There is also a spherical "no dead angle" camera in each car. The driver can observe the situation in each car and the opening and closing of each door through the monitoring screen in the control room to ensure the safety of passengers.
