Yes I was amazed to see this unless everything got fried cta will fix it just like they did 8194 a few years back if not it will retire

It could end up retired but it can be fixable since it is only going on 7 years old… Most likely it’ll be OOS for a while

Here’s the funny part tho my question is are we going through this once every year? #1993 caught fire in 2019, #1703 and #1757 in 2020, #6860 in 2021 and in the beginning of 2022 with #8144 the first 7900-series LFS to catch fire???? ????

This stuff always happens, including the 700 that had the fire that only the chicagobus.org people knew about, but it was rebuilt. Seems like  the overwhelming causes are brakes and tires, things which are within CTA's control.

#1703 caught fire in 2020? looking at 1703’s history in 2020 it ran all 12 months

The way the brake systems are designed,  it is very necessary for drivers to make sure their brakes are fully released.   Once upon a time a driver really only had to worry about that when releasing the parking brake.  Nowadays with brakes on the front and back doors, drivers have to give a full brake application before taking off.  Too many times I've seen buses taking off with the brake lights still on for a few seconds.  Obviously a driver can't see that, but he can tell if the brakes are fully released by letting the foot off the brake.  If the bus rolls freely,  then they are fully released. 

I haven't paid any attention to the tires on CTA or Pace buses.  Pasr experience has shown me that Firestone tires are more susceptible to failures than Goodyear.   However I don't know CRA'S tire rotation and changing patterns.

I'm not sure what tires are on the current buses, but the CTA used to use Goodyear City Cruiser tires, that had molded on the sidewall Maximum Speed 35 MPH!  That was on buses that used Lake Shore Drive.

I highly doubt they're using those now considering all the expressway use for deadheading

Naw 8144 is not the first 7900 to catch fire 8194 had a fire when it was still brand new years ago but it got fixed & put back on the road just like 8094 when it slammed into a building causing 100k in damages

So that makes #8144 the second one to catch fire

#8144’s fire was nearly the size of the issue of #1305 IMO?

Isn't there a fire suppression system in the engine compartment? Maybe that's why the fire didn't consume the entire bus.

Yeah in most terms, buses come with a suppression system installed, in case of a fire starts the bus won’t be completely burned. Yet I could be wrong

Yeah all buses come with it but in rare cases like this one here combustible components can overmatch any system. I got a good look at it last night and the damage resembles that of #1305 and #1150.  I'd give it six months to a year before #8144 gets any type of attention pending an investigation. I still believe the rear exhaust was the culprit based on where the fire started and concentrated the most.

Fure suppression systems keep fires contained or confined . Because fuel is very combustible,  keeping fires cinfined  is key.   Keeping the engine compartment closed until firefighters came was a key factor in keeping the bus salvaged.

chances are really low for #8144 to be repaired

Sadly if it doesn’t make it out of the woods, it’ll become a parts bus for the rest of the 7900-series if it doesn’t get fixed. I’ll say it only has a 2 out of 10 chance of getting repaired.
