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.
· Sound insulation performance improved, sound reduction index RW≥25dB
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 |
