A Standard gauge, high speed rail mass transit system with unique
feature of assuring that coach never can separate from rail tracks,
but uses all the proven, time tested railway technologies only.
Standard Gauge Rail tracks
60 kg rails fitted with double elastic fastenings, with Standard Gauge on
sleepers designed & tested for 20 t axle load norms forming maintenance
free tracks
Driving bogies:
100 kmph standard gauge 12 ton/14 ton axle load powered bogies -same
as used in metro rails with 4x110/115 Kw asynchronous 3 ph AC motors
with power-regeneration and capable of peak 1.3m/sec/sec acceleration
Braking:
Electrical re-generative braking, coupled with compressed air disk
mechanical brakes and emergency/ idling mechanical brakes for stabling.
Crushing load for underframe:
Underframe- fit to take crushloads of regular main line coaches- more than
70t
Train unit:
Each train unit 20m long with two driving bogies- the coach divided into
2x9.5 m long buses connected through vestibuled door
Capacity of 20m long train unit:
Each Skybus unit 20m long having two compartments( 3.25m x 9.5m) of
9.5 m , can carry almost 400 persons at 7 persons/sq.m density peak.
The 20 m units can be attached to form a 3 unit, 60m long train of 1200
persons capacity
Signal & train control:
Simple three aspect signal system driven by line of sight by motorman,
with additional unique safety layer of Raksha Kavach, capable of providing
40 sec headway- but planned 60 sec.
Route Capacity:
A Skybus route can thus be designed even at 60 sec headway, to carry
20,000 to 70,000 passengers per hour per direction in peak period.
Security and safety:
- Continuous computerised central monitoring & control with provision
of audio/visual access for each coach for security.
Distributed intelligence systems with redundancy to provide
protection against swinging under wind loads/emergecy localised
control/ prevent over-loading/ emergency evacuation guidance.
The reversal for the Skybuses at terminal points, to change tracks or go to
depots happens through traversers- mechanical auto driven systems
capable of handling 60m consists of Skybus units.
Stations-elegant and small:
Stations are 60m long to handle three units of Skybus, covering next 25
years of requirements-though initially only 20m length is needed.
Easy Access:
Access is from existing footpaths, climb limited to 6 m for passengers-
within 500 to 600m from wherever you are on the road having Skybus
route.
Turning radius & gradient:
Can be designed for 20m radius of turning radius, and vertical lift, if
needed- thus we can avoid totally demolition of any built up urban
property, if needed.
On line maintenance of rolling stock and tracks:
Maintenance is through continuous monitoring of vibration signatures, and
directed by need automatically by computerised systems- much more
advanced than existing manual inspections only and periodic checks.
All the sub-systems /elements are to existing UIC/Indian Railway codal
practices applicable to railway transport.
Cargo handling capability:
Cargo of standard containers are automatically delivered and cleared into
and out of city.
Safety Certification for Public carriage:
Will carry international class safety certification by renowned world class
safety certifiers.
Guaranteed against derailments and capsizing- making it a unique railway,
where coaches can never escape the tracks.
Terminal concept:
Current concept of a railway terminal replaced in this "grid" system, by a
multi point distributed discharge and access- almost eliminating inter-
modal transfers. Each station designed for handling whatever commuters
can arrive on a 4m wide foot-path- with waiting time less than one minute.
Land requirements for route, stations and at depots:
- All along the route the alignment is typically located on the median (
1.2m diameter columns at about 20m spacing) of the road, needing
right of way at 6.5m above the road, the fixed structure carrying
railway tracks located at about 11m- thus avoiding claustrophobic
effect for road users. Typical road widths normally of 10m all along
and at station locations 20m width for 60m length desirable.
Depots will be outside the urban areas, needing about 25 hectares
land for services for every 10 km route.
Stations are located with access from existing footpaths, and over
and above existing roadways, none of them longer than 60m to cater
to next 100 years of requirements of city- practically requiring little
land.
Typically for tropical climate conditions, for a module of 10 km route, 15
MW power needed covering traction and all services including comfort air-
conditioning loads at stations.
Quality of service and pricing:
With access within 500 to 700m walking distance, air-condition travel at
100 kmph , service available at less than a minute during peak hours,
priced at Re 1.50 per km falling to Re 1 for regular travels with lead of
more than 7km can be provided.(typical) (year 2005)- if ridership per a 10
km route is a little more than 3 lacs per day.
Typical costing ( Year 2005-06)
For typical installation to handle 40,000 passengers peak load per hour, on
a double line, the cost on turn key basis will be Rs 55 to 60cr per km, and
construction period less than 3 years, for a minimum module of 10 km
route.
( Typical and posted on 26 July 2006- being design requirements, we have
capability to alter/improve as situation demands)
