Which component of a tramway track structure directly supports the rails and distributes wheel loads to the ballast?
Fastening
Rail
Ballast
Sleeper
Sleepers (or ties) lie beneath the rails and transfer wheel loads into the ballast layer. They also maintain the correct gauge by holding rails at a fixed distance apart.
What is the primary purpose of ballast in a tramway track structure?
Provide a smooth running surface
Transfer electrical power
Support overhead lines
Distribute load and provide drainage
Ballast spreads and distributes loads from sleepers to the subgrade, while allowing water to drain away from the track. It also helps maintain track alignment under dynamic loads.
Which track component secures the rail to the sleeper?
Fastening system (clips)
Fishplate
Tie plate
Rail pad
Fastening systems, such as clips or bolts, clamp the rail flange to the sleeper and prevent longitudinal or lateral rail movement. This maintains gauge and track stability.
What device is used to join two rail ends together?
Fishplate
Elastic rail clip
Sleeper
Ballast
A fishplate (or joint bar) is bolted to the ends of two rails to hold them in alignment and transfer wheel loads across the joint. It provides a mechanical connection between rail segments.
Which personal protective equipment (PPE) is essential for all workers on a tramway construction site?
Hard hat
Safety harness
Welding gloves
Ear plugs
A hard hat is mandatory to protect workers from head injuries caused by falling objects or accidental impacts. Other PPE may be required for specific tasks, but the hard hat is essential site-wide.
Which surveying instrument is commonly used to check rail alignment and level in tramway construction?
Dynamometer
GPS receiver
Transit carrier
Theodolite
A theodolite measures precise horizontal and vertical angles on site, allowing engineers to verify that rails are correctly aligned and leveled. It is a standard tool in track surveying.
During ballast selection, what property of crushed stone ensures good interlocking and stability?
Spherical shape
Smooth surface
Uniform coloration
High angularity
High angularity of ballast particles promotes mechanical interlock under load, which increases track stability and resistance to movement. Rounded or smooth stones do not lock together as effectively.
Which method is typically used to compact ballast under tramway sleepers?
Laser leveling
Hydraulic pressing
Manual shoveling
Tamping with vibrating tamper
Vibrating tampers are standard equipment for ballast compaction because they deliver controlled vibration to settle ballast and ensure uniform support beneath each sleeper. This helps maintain desired track geometry.
For overhead line work on tramways, which specialized PPE is required to protect against electrical hazards?
Safety goggles
Steel-toe boots
Insulated gloves
High-visibility vest
Insulated gloves protect workers from electric shock when handling or working near live overhead lines. Other PPE may be needed, but insulated gloves are critical for electrical safety.
In tramway signaling, what does an amber (yellow) light typically indicate?
Stop immediately
Track ahead is clear
Caution, prepare to stop
Proceed at full speed
An amber signal warns the driver to proceed with caution and be prepared to stop at the next signal. It indicates that the block ahead may be occupied or that a red signal follows soon.
What is the purpose of interlocking in tramway signaling systems?
Record passenger counts
Prevent unauthorized track access
Allow simultaneous conflicting routes
Ensure safe clearance between trams by controlling signals and points
Interlocking links signals and track switches so that conflicting movements cannot be set simultaneously. This ensures that only safe, non-conflicting routes are given a proceed aspect.
What is a commonly recommended minimum distance between tram stops in urban areas to balance accessibility and travel time?
1000 meters
100 meters
500 meters
50 meters
A spacing of about 500 meters is often chosen in urban environments to provide reasonable access for passengers while maintaining efficient travel speeds and reducing dwell times.
During rail alignment inspection, what is the maximum allowable vertical deviation over a 3-meter chord typically?
10 mm
1 mm
3 mm
5 mm
A tolerance of ±3 mm over a 3-meter chord is a common standard for vertical alignment in tramway tracks, ensuring smooth ride quality and minimizing dynamic loads on the track structure.
What is a potential negative effect of over-compacting ballast beneath tram tracks?
Excessive track flexibility
Increased drainage capacity
Reduced water drainage and increased track stiffness
Improved resilience
Over-compacted ballast can lose its granular porosity, reducing drainage and leading to water retention. It also makes the track overly stiff, increasing impact loads on sleepers and rails.
What is the function of a tie plate in tramway track structure?
Secure overhead wires
Connect rail ends
Spread load from rail to sleeper and maintain gauge
Provide electrical insulation
Tie plates sit between the rail foot and the sleeper, spreading the wheel load over a larger area and helping to maintain the correct rail gauge. They also protect the sleeper surface.
For tramways on weak subgrade (CBR <5%), what is the minimum recommended ballast depth to ensure adequate support?
150 mm
300 mm
600 mm
450 mm
When the California Bearing Ratio is below 5%, a ballast depth of at least 300 mm is typically recommended to distribute loads effectively and protect the weak subgrade from excessive stress.
In designing transition curves, which parameter A in a clothoid defines the rate of change of cant and curvature?
Superelevation
Clothoid constant A
Cant gradient
Radius of alignment
The clothoid constant A determines the rate at which curvature - and thus cant - changes along the transition curve, ensuring a smooth change from straight to curved track.
Which advanced signaling technology allows real-time tram location tracking and dynamic priority at intersections?
Timetable-based signaling
Communications-Based Train Control (CBTC)
Mechanical interlocking
Fixed block signaling
CBTC uses continuous communication between vehicle and control center to provide precise location data and can dynamically adjust signal aspects for tram priority at intersections.
Which GIS-based analysis technique is most effective for optimizing tram stop placement based on pedestrian accessibility?
Cluster sampling
Topographic mapping
Buffer zoning
Service area (isochrone) mapping
Isochrone mapping generates service areas around stops based on walking time or distance, allowing planners to visualize coverage and adjust stop locations for optimal pedestrian access.
What neutral rail temperature is generally targeted during continuous welded rail installation to minimize thermal stress?
0 °C
45 °C
15 °C
27 °C
A neutral rail temperature around 27 °C is commonly specified for stress-free welding and installation of continuous welded rail, minimizing tensile or compressive thermal stresses in service.
