I think that the authors solution, outsourcing production is not quite right, they gloss over other issues.

>In a large country like the US, some variation in bus design is inevitable due to differences in conditions like weather and topography. But Silverberg said that many customizations are cosmetic, reflecting agency preferences or color schemes but not affecting vehicle performance.

This is kind of absurd, I have been on busses all over the country, a metro bus, is a metro bus. There are not really differences based on topography or climate.

>Two US transit agencies, RTD and SORTA, bought similar 40-foot, diesel-powered buses from the same manufacturer in 2023, but RTD's 10 buses cost $432,028 each, while SORTA's 17 cost $939,388 each.

The issue here appears to be: Why is SORTA's purchasing so incompetent that they are buying 17 busses for the price of 35? They are over double the price of RTD.

> That same year, Singapore’s Land Transport Authority also bought buses. Their order called for 240 fully electric vehicles — which are typically twice as expensive as diesel ones in the US. List price: Just $333,000 each.

Singapore has a very efficient, highly trained, highly educated, highly paid administrative staff, and their competency is what is being shown here. They thought to get a reduction in price because of the large number of busses they are ordering.

One solution the author doesn't point out is that Federal funds often come coupled with a large amount of bureaucratic red tape. It could be cheaper in the long run to have more tax collection and expenditure at the local level, and not rely as much on federal grants.

It definitely depends. The traditional yellow school buses here (Canada) use diesel, so they need things like glow plugs [0] and block heaters [1] to be able to run in the winter. But even that only helps so much, so when the nighttime lows are below –40°C, they cancel the busses since they know that they won't run.

Most of the city busses here use natural gas, and they're considerably more reliable in the cold weather but if they're parked for too long on a really cold day (even while running), the brakes will freeze up and they won't be able to move [2].

Similarly, the busses need a fairly powerful heating system, since it's tricky to heat a large space when it's really cold and the front door is open half the time. But conversely, most of the busses have no A/C.

Adding glow plugs, and block heaters, and brake dryers shouldn't cost hundreds of thousands of dollars, but a more reliable natural gas bus might be double the price of an unreliable diesel one.
