Not long after electrical power was first harnessed, trolley cars began carrying passengers, getting their electric power from overhead wires. The trolley’s pantograph makes contact with the electrified wire to send power to the motor that turns its wheels.

By the 1920s, 17,000 miles of wire-linked electric streetcar lines ran through American cities. Today, the noble trolley is largely a curious memento of a bygone era – before automobiles and big, mobile buses began crowding urban streets.

In the interim, once-profitable trolleys were absorbed by conglomerates, and local governments began dictating trolley routes, fares, and times of service. Many eschewed the wisdom of dedicated routes and let trolleys get bogged down by traffic. Diesel-powered buses soon became the favored mode of public transport, all too often requiring growing subsidies to remain afloat.

Corruption, mismanagement, and a lackadaisical attitude toward service excellence have plagued public transportation almost from the day that the government and monopolists ran off the last small, independent trolley line operators.

By the 1930s many streetcar companies had switched to diesel-powered buses, which were cheaper and more flexible, and the trolley in most cities faded away only to resurface decades later as “light rail.”

Twenty years ago the Federal Reserve Bank of St. Louis posed the question whether the social benefits of light rail outweigh its costs. The essay assumed that transit must be publicly owned and regulated – yet the very history of the trolley shows that as soon as government took control, once-profitable vehicles became a huge liability.

The most shocking revelations in the Fed’s essay were that fare revenue covered so little of the operating cost (let alone maintenance, expansion finance, or other things real businesses must find answers for): St. Louis 28.2 percent; Buffalo, 21.4 percent; Baltimore (19.4 percent). The Fed’s conclusion? No privately owned system could ever be built or operated with such a dismal balance sheet.

The Fed made two errors. First, not calculating whether the public investment would stimulate the local economy enough to justify the cost. Second, not comparing the cost of allowing private entities to bid for individual routes.

Throwing public dollars at public transportation has long been popular among city mayors and increasingly with the federal government. It’s other people’s money, but you get the photo ops.

Recently, though, people have been complaining that this battery-electric bus craze was not their idea, but part of an elitist-inspired, poorly thought-out “drive to Net Zero.” Having gone into debt from round 1 of electric buses, cities gushed as President Biden allocated $7.5 billion to “stimulate” more purchases and thus more public debt.

Philadelphia’s SEPTA transit was an early purchaser of battery-electric buses, but as reporter Ryan Briggs wrote in 2021, “$2.6 million [already spent from a federal grant] and 25 broken buses later, the agency [was] rethinking its approach.”

The city’s electric buses, introduced in 2019, sat idle in a bus depot two years later, “riven by cracked chassis and other defects,” with no timeline for return to service.

President Biden visited bus manufacturer Proterra, for whom his Energy Secretary Jennifer Granholm had once served as a board member.

Proterra buses were removed from service in Duluth, Minnesota after local officials saw that hilly routes and winter heaters drained their batteries too quickly. Indianapolis idled its BYD (Chinese) buses that had charging life issues. Albuquerque returned 15 BYD buses for the same reasons. The list is long.

The battery-electric bus nightmares continue. Just last month Edmonton, Alberta, city officials admitted it was a giant mistake to order sixty buses from now-bankrupt Proterra. Now the city is seeking over $82 million in damages from Proterra because buses failed to meet expected mileage ranges and had various hardware and body issues.

According to the proof of claim, “None of the buses achieved 203 miles on a single charge. On average, the bus range has been approximately 103 miles in winter and, at best, 155 miles in warmer weather.” Moreover, because of hardware issues, more than half were out of service on an ongoing basis.

Just days ago the Milwaukee County Transit System was ready to throw in the towel 15 months after putting 11 electric buses online. “Since it’s an infancy technology, not a lot of properties have been able to make a full transition over,” said MCTS enhanced transit manager David Locher. As in Duluth, only half the city’s electric buses were on the streets on a typical day.

Similar woes have plagued transit systems in Asheville, Colorado Springs, Austin, and other cities that have spent up to $1.2 million per often-idled bus. Still, the carnage continues.

Michigan Governor Gretchen Whitmer, who envisions her state with 2 million electric vehicles by 2030, wants to replace 17,000 school buses, at a cost exceeding $6 billion, starting in “297 priority districts” mainly in rural and low-income areas, all by leveraging a $125 million EPA grant. Prospects are Michiganders will be on the hook for many times that amount.

The mother of all electric bus nightmares, though, may be in London, England, where neither cost nor range nor frequent maintenance is the chief concern. In a two-day period in early January, an electric double-decker bus exploded and another London bus burst into flames. Both were completely destroyed. These fires came less than two years after six buses burned in Potters Bar, prompting other bus operators to move vehicles from alternative garages.

Still, in January, another fire caused bus company Go Ahead London to launch a “precautionary fleet check” of 380 of its electric buses. Six weeks later, the Driver Vehicle Standards Agency issued an emergency recall of 1,759 electric buses operating in and around London after identifying a fire risk in the US$1 billion fleet’s air conditioning and heating system.

According to the agency, there is no permanent solution now available to prevent future bus fires. Instead, operators of the high-tech buses are warned to “switch off the Hipsacold HVAC system if the vehicle is left unattended.”

Such is the level of threat posed by electric bus fires, the London Fire Brigade is rewriting its operations manual on dealing with these incidents. One new provision requires that in the event of a fire on an electric bus, a specialist hazardous materials officer must be sent to the scene, along with at least two fire engines.

The flap has extended to the political scene, as the “heat” on longtime London Mayor Sadiq Khan intensifies. Reform UK candidate Howard Cox had predicted that “rushing into new idealistic based choices” could create problems. He added, “The rosy picture of the promise of zero emissions has clouded ill-informed politicos’ judgments to ignore safety issues and the cost of replacing reliable and proven safer lower cost diesel buses.”

Fire is just one reason many cities are rethinking their commitments to battery-electric buses (which, being heavier, also tear up city streets quicker). Meanwhile, the largest trolley fire on record may be the one 21 years ago that tore through the National Capital Trolley Museum, destroying eight historic streetcars long since retired from service.

That said, maybe they should have stuck with trolleys – and diesel buses.
