Product overview
The Interconnecting Gangway is installed at the junction of the adjacent two carriages at the end of the vehicle, so that the two carriages form a complete passage. The Interconnecting Gangway is the passage to connecting entering and leaving between two carriage. It has good longitudinal flexibility and lateral and vertical flexibility to meet the requirements of vibration during vehicle operation and safe passage of curves and turnouts.

Product advantages
Compared with rubber gangway, pucker vestibule gangway has below advantages:
· Air tightness improved, the leakage time when the air pressure in the gangway drops from 3600Pa to 1350Pb is not less than 50s.
· Ability to pass curves improved, the minimum curve radius that can be passed when connecting is as low as to R145M
Below is there different types of Interconnecting Gangway FYI
| S.No. | Type | Features | Picture |
| 1 | EMU High-speed Train Gangway | Small passage width |  |
| No interior panel (roof panel & side panel), simple structure | |||
| High requirements to sound insulation, thermal insulation, air tightness | |||
| Meet the aerodynamic load requirement for trains meeting with high speed | |||
| 2 | Metro Gangway | Big passage width | |
| Most of projects have interior panel | |||
| Sound insulation 27~40dB, no air tightness requirement; | |||
| Meet the requirements of quick connection and disconnection | |||
| 3 | Tram Gangway | Big passage width, outer profile is almost same size as car body | |
| Usually without interior panel | |||
| Sound insulation 12~25dB, no air tightness requirement | |||
| Puckered type, meet small curve passing requirement |
