Abstract

Abstract A system interlocking trains whereby passengers and/or goods may be transferred therebetween while the trains are in motion. The system includes means for interlocking a train travelling on a main line with a train travelling on a local line, and means for providing transfer of passengers and/or goods therebetween while the trains are in motion. Local trains run on local lines spaced at desired locations along the main lines. After the transfer of passengers and/or goods is completed, the trains are decoupled, whereby the main train continues en route and the local train may be unloaded. Wind deflectors are provided to deflect any wind factor which might develop during transfer of passengers and/or goods. Floors are extended laterally from the side of each train to form a passenger bridge to transfer passengers therebetween. The bridges are provided with curtain roofs which are extendable from the top of each train. Prior to disengagement of the trains, the curtain roof is moved into contact with its respective floor and, as the floor is retracted back into its respective train, the curtain roof moves therewith to assure that no passengers are left on the bridge as the extendable floors are retracted.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 119 words
In a railway system wherein a main train and a local train may be interlocked to travel in synchronization for transferring passengers therebetween, the improvement comprising: a floor extendible from the main and local trains after they are interlocked to form a passenger bridge therebetween, a curtain roof extendible from the main and local trains concomittantly with the floors to provide a ceiling enclosure for the passenger bridge, the curtain roofs being extendible to their respective floors in fixed connection therewith after transfer is completed, means to retract the floors and their connected curtain roofs after transfer to within their respective trains, and means to release the curtain roofs from their respective floors after the latter are fully retracted.
Claim 2
Dependent Claim 119 words
In a railway system wherein a main train and a local train may be interlocked to travel in synchronization for transferring passengers therebetween, the improvement comprising: a floor extendible from the main and local trains after they are interlocked to form a passenger bridge therebetween, a curtain roof extendible from the main and local trains concomittantly with the floors to provide a ceiling enclosure for the passenger bridge, the curtain roofs being extendible to their respective floors in fixed connection therewith after transfer is completed, means to retract the floors and their connected curtain roofs after transfer to within their respective trains, and means to release the curtain roofs from their respective floors after the latter are fully retracted.
Claim 3
Dependent Claim 27 words
The railway system recited in claim 1 further comprising means connectable to the front of the main and local trains to push air to the sides thereof.
Claim 4
Dependent Claim 31 words
The railway system recited in claim 1 further comprising: retractable means connected to the main and local trains actuable during transfer to be extended to form a buffer to deflect wind.
Claim 5
Dependent Claim 27 words
The railway system recited in claim 3 further comprising means connectable to the front of the main and local trains to push air to the sides thereof.
Claim 6
Dependent Claim 80 words
In a railway system wherein a main train and a local train may be interlocked to travel in synchronization for transferring goods therebetween, the improvement comprising: conveyer means extendible from the main and local trains after they are interlocked to form a transfer system therebetween, means to retract the conveyer means after transfer of goods is completed, and retractable means connected to the main and local trains actuable during transfer to be extended to form a buffer to deflect wind.
Claim 7
Dependent Claim 80 words
In a railway system wherein a main train and a local train may be interlocked to travel in synchronization for transferring goods therebetween, the improvement comprising: conveyer means extendible from the main and local trains after they are interlocked to form a transfer system therebetween, means to retract the conveyer means after transfer of goods is completed, and retractable means connected to the main and local trains actuable during transfer to be extended to form a buffer to deflect wind.
Claim 8
Dependent Claim 27 words
The railway system recited in claim 5 further comprising means connectable to the front of the main and local trains to push air to the sides thereof.
