Questions Asked in Contributing to Monorail System Improvements Interview
Q 1. Explain the different types of monorail systems and their relative advantages and disadvantages.
Monorail systems are broadly classified into two main types: straddle-type and suspended-type. Both run on a single track, but their designs differ significantly.
- Straddle-type monorails: The train straddles the track, with wheels running on either side. This design is generally simpler and less expensive to build, making it suitable for shorter lines or less demanding environments. Think of it like a train running on a giant, elevated beam. Advantages: Relatively simpler construction, lower initial cost. Disadvantages: Higher center of gravity can lead to instability at high speeds, limited passenger capacity compared to suspended types.
- Suspended-type monorails: The train hangs underneath the track, suspended from it. This design allows for higher speeds and smoother rides due to a lower center of gravity. It’s like a train hanging from a large, inverted ‘U’ shaped track. Advantages: Higher speed potential, smoother ride, potentially greater passenger capacity. Disadvantages: More complex construction, higher initial cost, requires more robust support structures.
The choice between these types depends heavily on factors like terrain, passenger volume, budget, and desired speed. For instance, a short, tourist-oriented monorail might utilize a straddle-type system, while a high-speed transit line in a major city would likely opt for a suspended design.
