An intercommunicating passageway (9) between double-decker articulated railway coaches (1) including a wheel frame (10) with a lowered center section (11) and a pair of wheels (12a, 12b) are at an area between two successive coaches, which have a lower passenger room (7) with a first floor (3) at a first lower level (H1a) between pairs of wheels, and an upper passenger room (8) with a second floor (4) at a higher level (H2), on top of said lower passenger room. In the passageway a first bridge (5) extends between two successive coaches, the first bridge being at a second lower level (H1b) on the first floors, and a second bridge (6) extends between the two successive coaches, the second bridge being substantially in the same higher level with the second floors of the coaches connected. The first and second lower levels (H1a, H1b) of the first floors and the first bridge are down from the highest peripheral point (P) of the wheels.

1. An intercommunicating passageway between double-decker articulated railway coaches, comprising in combination:A wheel frame at an area between two successive coaches, and having a lowered center section transverse to a length direction of the coaches, and a pair of wheels supported by and connected through separate bearings without a common shaft to said wheel frame, said wheels having a large rolling diameter for high speed and load bearing capacity, Said coaches having a lower passenger room with an inner height and a first floor at a first lower level between pairs of wheels at the ends of the coaches, an upper passenger room with an inner height and a second floor at a higher level, on top of said lower passenger room, and a height portion between the upper limit of a standard kinematic gauge and said wheels smaller than the sum of said inner heights, In said passageway a first bridge extending between the two successive coaches, the first bridge being at a second lower level which is above the first floors of the coaches connected, a second bridge extending between said two successive coaches, the second bridge being substantially in the same higher level with the second floors of the coaches connected, and said first lower levels of the first floors and second lower levels of the first bridges are down from the highest peripheral point of said wheels. 2. The intercommunicating passageway according to claim 1, wherein said first lower levels of the first floors are substantially at a height of a common axle line of said pair of wheels.3. The intercommunicating passageway according to claim 2, wherein said second lower levels of the first bridge are closer to a common axle line of said pair of wheels than the highest peripheral point of said wheels.4. The intercommunicating passageway according to claim 1, further comprising a lower walkin above the first bridge, continuing from the lower passenger room in one of the successive coaches to a lower passenger room in another of the successive coaches, said lower walkin having an inner height approaching that of the lower passenger rooms.5. The intercommunicating passageway according to claim 1, further comprising an upper walkin above the second bridge, continuing from an upper passenger room in one of the successive coaches to an upper passenger room in another of the successive coaches, said upper walkin having an inner height approaching that of the upper passenger rooms.6. The intercommunicating passageway according to claims 4 or 5, wherein said upper walkin has an inner width and the lower walkin has an inner width, which are substantially smaller than inner width of the lower and the upper passenger rooms, respectively.7. The intercommunicating passageway according to claim 1, wherein the inner height of the lower passenger rooms is substantially equal with the inner height of the upper passenger rooms.8. The intercommunicating passageway according to claim 1, wherein said first bridge extends from coach to coach between the wheels of said pair of wheels and above the lowered center section of the wheel frame.9. The intercommunicating passageway according to claim 1, wherein said successive coaches further comprise two pairs of connection rods therebetween, said connection rods in both pairs being longitudinally successive and interposed through articulations by a control lever pivotally secured to one of transversally opposite end regions of the wheel frame, and said connection rods being coupled with stationary articulations with the mutually opposite ends of the successive coaches.10. The intercommunicating passageway according to claim 1, wherein one of the successive coaches comprises locks attaching said first and said second bridge to the coach pivotally around a vertical line.11. The intercommunicating passageway according to claim 10, wherein another of the successive coaches comprises a pair of side stops fixed in said first floor and in said second floor, said side stops located transversally at both sides of the first and the second bridge.12. The intercommunicating passageway according to claim 1, wherein said first bridge and said second bridge rest against the first floor and the second floor, respectively.13. The intercommunicating passageway according to claim 1, wherein said coaches further comprise suspension means mounted between the wheel frame and a coach body at two points having a spacing therebetween in transversal direction of the coach, and a lower walkin extending from coach to coach along said spacing.14. The intercommunicating passageway according to claim 13, wherein the other of the two successive,coaches is supported via at least a pair of carrying bars at both longitudinal sides of the coaches.15. The intercommunicating passageway according to claim 1, wherein said coaches further comprise at least one bellows means surrounding the passageway; and that the bellows means are positioned substantially inwards from the kinematic gauge applied.16. The intercommunicating passageway according to claim 1, wherein said lowered section is down from said common axle line.17. The intercommunicating passageway according to claim 1, wherein said successive coaches further comprise coupling rods with an articulation connecting said coaches without contact with the wheel frame.18. An intercommunicating passageway between double-decker articulated railway coaches, comprising in combination:A wheel frame at an area between two successive coaches, and having a pair of wheels with a common axle line but not a common shaft supported by and connected through separate bearings to said wheel frame, and a lowered center section, which is down from said common axle line; Said coaches having a lower passenger room with an inner height and a first floor at a first lower level between pairs of wheels at the ends of the coaches, an upper passenger room with an inner height and a second floor at a higher level, on top of said lower passenger room, In said passageway a first bridge extending between two successive coaches, the first bridge being at a second lower level which is above the first floors of the coaches connected, a second bridge extending between said two successive coaches, the second bridge being substantially in the same higher level with the second floors of the coaches connected, and said first lower levels of the first floors and second lower levels of the first bridges are down from the highest peripheral point of said wheels. 19.
