Through travelling, I found lots of European towns now utilise a fleet of small electric buses rather than large traditional buses.
This got me thinking: as an outer suburb resident, a few issues I have with the existing bus routes:
- They run every 20 minutes while the trains run every 10 minutes.
- Diesel buses are loud.
- I never see more than 20 people on a bus, even during peak hours.
- Only a few bus routes available.
- Noisy in the residential areas.
- Electric buses cost about 1 million each and we are yet to see any on our routes.
Will it be better to replace the low patronage, train station feeder routes (not arterial or inner suburban routes) with smaller electric buses, and doubling the frequency? I use the Yutong E7S as an example for comparison with a Volgren Optimus:
- Lower capex per bus: A small electric bus cost much less than a large diesel bus, and significantly less than a large electric bus. Gemini’s estimate is 1/2 of a standard diesel bus cost or 1/3 of a standard electric bus cost.
Edit: as many pointed out, drivers wage is a the largest part of the running cost, but so is the cost of borrowing.
Vic Gov 15-year bond is at 6.35% interest rate.
Assuming an electric full size bus is $1 million, a small electric bus at $300k: $1m borrowed over 15 years becomes $1.55m, and $300k borrowed over 15 years becomes $466k.
The gap in total cost is $1.087m, or $72.5k per annum over 15 years. This leaves a lot of room to improve staffing.
- Lower opex per bus: small electric buses don’t consume the expensive diesel, much lower cost of servicing & tyres.
- Thus more buses can be purchased and more drivers can be hired on a similar budget.
- Smaller buses are easier to drive for the drivers.
- E7S as an example, requires exactly half of a standard bus’s parking lot size. Less real estate needed for bus depots.
- Our local bus routes are 5-10km each way, and range is not a concern.
- Less wear and tear on the roads as they are 3/5 of a standard diesel bus’s tare weight.
- Quicker to accelerate and decelerate, fewer collisions with parked cars on narrow streets
- Smaller turning circle & less restricted bus routes
- Less noise and no idling noises. Electric depots can be placed closer to residential areas where they need to be, rather than industrial areas.
