The fire then moved down the row, catching several others on fire, leaving charred remains of the vehicles.
SMART buses come equipped with diesel engines that require being kept warm during winter months. Instead of using spark plugs, the transport vehicles use something called glow plugs, which hook up to the engines.
According to the Deputy Director for Community Development of Westland, a SMART bus caught fire due to the hookup.
From there, the fire apparently hopped down the row of buses, torching them and leaving shells of their former selves in its wake.
Smoke could still be seen from one of the carcasses hours after the fire had been put out.
The damage was reported on six of the vehicles, as well as the pavement where they were parked and a shed behind them.
Nobody was injured.
The seniors that rely on the vehicles won't see their daily routines disrupted, however, since several other buses are still in working condtiion
