CBC Radio-Canada has obtained audio recordings of communications that took place on the night of the Lac-Mégantic train disaster, which killed 47 people and destroyed the downtown core of the small Quebec town last year.

The recordings are of conversations between the train engineer, Tom Harding, and a dispatcher at the offices of Montreal, Maine and Atlantic Railway, the operators of the train, which was carrying 72 tanker cars full of crude oil when it derailed and exploded.

The recordings were obtained through Harding's lawyer, Tom Walsh. They contain all seven calls that Harding made between 11:04 p.m. ET on July 5 and 3:53 a.m. ET on July 6 in the order in which they appear in the transcript below.

The transcript is an edited version of one provided to CBC by The Globe and Mail.

RJ: CCF Farnham.

TH: Has it calmed down at your end, RJ?

RJ: No.

TH: F--k. OK. So what are you gonna do with me? You know there’s no trains by for a couple of days — they’ve got to rebuild the tracks, eh?

RJ: Yeah.

TH: Yeah. The couple of the box cars have burnt at the west end of the yard and all of his ties are gone - the ties he’s got there. Nasty fire. Now they’ve got a couple of pelles mechaniques and dump trucks; they’re trying to put out the fire that’s stopping them from working, which is the natural gas line behind the Jean Coutu.

RJ: Oh, yeah?

TH: Yeah, that’s uh, that’s the problem right now. They can’t, they can’t do anything anywhere until they get that put out, so they’ve got dump trucks and pelles mechaniques, and the pelles mechaniques were up on the tracks. It has to be all inspected tomorrow there.

RJ: Bon uh...

TH: They go up the embankment between the station and the bridge over the river.

RJ: OK, but it’s worse than that, my friend.

TH: No!

RJ: Yes, sir.

TH: No, RJ.

RJ: Yes, sir.

TH: Holy f--k. F--k!

RJ: Yes, sir. That’s what I got. It was confirmed at 2:30.

TH: The units, the V.B., and the first car. Seven brakes.

RJ: Well, uh,  I don’t know what will happen. The best I can tell you is that Daniel Aubé is on his way to get there …

TH: OK, well what’s, what you want to do with me, RJ? You’re not gonna lleave me out in the cold here.

RJ: I don’t know. As soon as I got some news, I just asked Jean,  Jean Demaitre, he called me a couple of minutes ago. I just told him that you’re stuck there and you’re gonna be with Samson there. So I said what are you gonna do with those guys? He said I don’t know I’ll come back to you on that.

TH: F--k. I’m at a payphone here, RJ, I got no way to talk to anybody anywhere.

RJ: Um …

TH: Oh, Jesus Christ …

RJ: You got the 1-800 number here, OK.

TH: The what number?

RJ: To call me, to call me.

TH: Yeah well that’s what I did …

RJ: Yeah, yeah.

TH: Holy f--k.

RJ: Yeah, yeah, that’s the news that I got.

TH: That the f--king fuel train rolled down, it was a question of... anyways. …Son of a bitch. Was there any railway people that went up there to put the fire out on that… (inaudible)?

RJ: Jean-Noël Busque went there.

TH: And everything was secure when he was there? Everything was fine? Everything was …

RJ: Everything was fine, yeah.

TH: And then it rolled down, what, two hours later? Three hours later?

RJ: Well, uh, fire was out at midnight, and I got a call at 1:30 that there was a fire in downtown.

TH: (pause) There’s no way to talk to me, RJ, I’ve got my radio on channel 20 right now… Uh, f--k. Dan Aubé is on his way, can he come to me?

RJ: I don’t know if he’s gonna be able to. Apparently the city is cut in two. From what I heard from Jean-Noël Busque, there.

TH: Yes?

RJ: He finally made it to Nantes …

TH: Yes?

RJ: … to confirm me that the train was not there anymore.

TH: And here the police, they confirmed to me, RJ, when I talked to you at the very, very beginning – they confirmed that the train was up there. What did it hit? I don’t understand, RJ, if it rolled down...

RJ: Apparently, it rolled down.

TH: OK, and where did it stop?

RJ: Can it be at the curve, at the crossing there?

TH: What? It derailed at the curve, that’s what happened?

RJ: Can it be? I don’t know.

TH: Yes, it’s possible, RJ, it’s possible, but it’s uh…

RJ: That’s what I think. It would be the only thing that would … when it hit that f--king curve there it must have derailed. I’m not sure.

TH: F--k!

RJ: That’s, that’s the only … you know what? I’m down here, hey, and I get the infos that I …

TH: what people are telling you.

RJ: Yeah, that’s it.

TH: And I’m going by what the people are telling me here, too.

RJ: Yeah, that’s it.

TH: Because they, they told me it was tankers that were blowing up here, at this end here.

RJ: So as soon as I have some news…

TH: Call me on channel 20. I’m standing next to the phone here, I’m out in the f--king freezing cold.

RJ: OK, as soon as I get some news there, I’m going to give you a yell. But you cannot go back to the Auberge?

TH: No, i can’t. I got half of my stuff still at the Auberge. I can’t. There’s no way. No way I can go anywhere, I can’t do anything anywhere.

RJ: OK.

TH: When you get a hold of Jean Demaitre, I’d like to speak with Jean.

Final transcribed conversation

[July 5, sometime between 11:05 p.m. and 11:45 p.m.]

Harding talking to a U.S. rail traffic controller

RTC: Dispatcher’s office.

TH: Yeah, Glen, Tom here. I’m up here at Nantes. Shut down four of the five units, got the hand brakes applied. Do you have any questions for me?

RTC: No, no. I’m all set Tom, tied down at Nantes, just get me a yell when you’re off time.

TH: OK, I just thought I’d mention to you there, Glen, uh, the 5017, I worked her pretty damn hard coming up here. She’s smoking excessively now. I know it’s going to settle down once she cools down and stuff like that. I don’t know how good it’s going be on the eastbound now. When I left Farnham, I had engine hunting [sic] on it, I got it to settle down when I started using the seventh notch only, and it pulled real nice, and this last little pull here from the bottom of the hill at 26, down at Scotstown, all the way up to here, she worked pretty damn hard. Once I got stopped here, I only noticed when I got stopped here, that she was smoking excessively both black for a minute or so, and then she’d go white for a little bit, and then go back to black again.

RTC: Well you probably cleaned her out, Tom. This is Dave.

TH: Oh, this is Dave. OK, yeah. Could be I cleaned her out ... I’ve been here, you know, for 10 minutes. The smoke has cleared. Well, I should say there’s less smoke coming out of it right now. It’s still changing colour back and forth, black and white, black and white, a little bit there, but, maybe if she sits here for another hour or so, she will cool right down.

RTC: Well, that’s all we can do, Tom. We’ll check it in the morning and see what she says and see what she comes up with. Diagnose her then, I guess. Over.

TH: OK, I understand. I understand. What time is the eastbound engineer ready to go tomorrow?

RTC: 7:30, over.

TH: 7:30, OK. Well, we’re pretty much..pretty darn close. I should be like a half hour behind him, then.

RTC: Yeah OK. Yep. Just uh, you let RJ know...Talk to RJ or how he wants to do it. Over.

TH: OK, Dave. I’ll check back with you a little later.

RTC: MMA Northern Maine out.

TH: Tom Harding out.
