If you follow DCTP's spoiler cbox, you've already seen these summaries and translations. While the file will likely be out soon and this post rendered useless, in case you wanted in depth descriptions before then, here they are with credit to the translators who did them. Some minor changes to the page numbers were made.
Mina: I will try my best to translate each speech bubble, some translation might be a little too direct, I apologize in advance.
Mina: Page2: Passenger "What do you mean fire?!" "Explain properly!" Conductor: "Ah, well, we haven't grasped the situation either... we will announce it once we understand it"
Mina: Kogorou coughing. Agasa: "Ohh Mouri-kun!" Ran: "Dad! Where are Conan-kun and Sera-san?" Kogorou: "I was with the kid with glasses until just now but.. that tomboy-ish girl should have gone to you
Mina: a while ago" Sonoko: "She hasn't come!"
Mina: Kogorou: "Maybe she got lost on the way..." Ayumi: "What about Ai-chan?" Genta: "She went that way right?" Mitsuhiko: "Isn't she with Conan-kun?"
Mina: Kogorou: "I don't know. Isn't she around there somewhere?" Ran: "What do you mean somewhere there?"
Mina: Page 3: Vermouth: "That's right... if it's her, she'll head toward the the 8th car, the source of the fire... " "She'll realize that this smoke is a trap by the organization to lure her out.."
Mina: Yukiko: "I see! She realized that if she went to front car, you(the BO members) will be awaiting her there". Vermouth: "You don't get it do you. Her friends have also escaped to the front car"
Mina: "if her targeted self goes there, they'll get involved as well, especially since it seems that the kids has met her in her former appearance"
Mina: Vermouth: "that's why she'll go toward the fire... even if she knows the organization might bewaiting in the 8th car" "She'll think it's better to be the only person killed"
Mina: end of of page 3 & into page4: Yukiko's phone rings, it's from Conan/Shinichi. Vermouth answers, using voice of Yukiko. Conan in panicked voice says that he can't find Haibara, and asked if she has come to her.
Mina: Vermouth (in Yukiko's voice) suggests that Haibara probably went to front car, since she could hide among the crowd. Conan saysthat he'll go ahead to front car and reminds her to do their plan well
Mina: Vermouth gets mail from Bourbon an tell Yukiko that they found Ai/Sherry in 8th car, and tells her that it looks like it's their win.
shuu: Page 5 with Bourbon talking to Sherry, referring Moroboshi Dai:
shuu: Bourbon: Bourbon… This codename, do you remember hearing? Though I’ve met your parents and your sister…
shuu: Sherry: Yeah… I know… That there’s a member of the organization who has a rival relation with oneechan’s boyfriend Moroboshi Dai. According to what oneechan told me, you seem hate each other…
shuu: Bourbon: Yeah… He’s a dog of FBI… After betraying the organization, it’s hard to believe that he’s been killed…
shuu: Bourbon: So disguising as that man, I’ve been going around people related to him to see their reactions. Fortunately, I found out that the man is really dead.
shuu: Bourbon: Maa, this time my nakama as been disguising as that man instead of me. That you showed up here means that you seem’ve got enough of terror
shuu: Bourbon: The one who disguised as that dead man, you also know her well... Now, let's keep your hands up and move to the back of car number 8
Mina: Page 6: Vodka mentions how C4s are set to blow up just as the train arrives. Gin comments of what a good coincidence that the head of Suzuki and the top of Aichi police force are also on the platform
Mina: Gin comments that thanks to their presence, the explosion will be seen to be targeting them instead of passengers on the train. Vodka asks how Vermouth and Bourbon will escape from the train
Mina: Gin basically says he doesn't care. Vodka, much to Gin's surprise, mentions how Vermouth asked for the left over C4, though she wouldn't tell him what it's for.
Mina: Gin seem to be able to guess what Vermouth might do
Mina: Page 7: Bourbon explains to Sherry how he's planning take her back to BO alive. He'll separate the last car with explosive and once the car stops, awaiting helicopter will collect unconscious Sherry.
Mina: He tell her not to worry about explosion since she'll be sleeping in area away from the explosion but Sherry points out that's not the case
Mina: Page 8: Sherry points out that the entire luggage car is rigged with explosives. Bourbon realizes that Vermouth wants to kill Sherry no matter what.
Mina: Bourbon then asks her to come with him but Sherry declines and slams the door.
Mina: Bourbon notices figure behind him
Mina: page 9: He think it's Vermouth and starts to tell 'her' that he'll be taking Sherry with him but is interrupted when the figure throws a hand grenade at where he's standing.
Mina: Bourbon realizes it's not Vermouth and shouts at the figure, asking who he is. (It's Akai!! )
Mina: page 10: Bourbon just curses when the grenade explodes, separates the luggage car, and the luggage car also explodes
Mina: Page 11: Vermouth says that its "the end". She tells Yukiko not to worry about the rest of train derailing because her partner confirmed that the luggage car exploded after it had separated from the
Mina: rest of the train
Mina: Yukiko acts panicked and starts to call out "Ai-chan" but stops as soon as Vermouth leaves the room.
Mina: The train conductors comment to each other about whether the luggage car really did explode. The younger one comments that he saw black smoke. Bourbon is thinking to himself "That figure, could it be?"
Mina: Page 12: Vermouth informs Gin that Sherry is dead, saying Bourbon saw the entire luggage car explode. Because of that, the train stopped in the nearest station
Mina: The passengers were told to get off and are about to be asked questions one by one.
Mina: Gin realizes that the reason she used explosives is because she knows the train will be forced to stop before the last stop. Vermouth comments that it should be enough that only Sherry is blown into bits
Mina: As soon as she hangs up her phone, Mitsuhiko comments about how he was surprised...
Mina: onto Page 13: how Haibara was in the B room of 7th car. She felt dizzy on the way back from bathroom so she rested in that room, since it was open. (or at least that's what the kids were told, of course)
Mina: Vermouth deduces that Yukiko figured Haibara will run into that room and took her to safety. She also realizes that Conan was listening to her conversation with Yukiko and the phone call was a fake to keep her in the room
Mina: As she's wondering who was the girl that got blown up, Sonoko comments about her disappointment that Kid can no longer come. Vermouth makes realization. Conan is the phone, sort of apologizing about things were kind of close
Mina: Page 14: It's Kid, in Sherry disguise, escaped on hang-rider. He annoyingly comments to Conan, about gun and explosives being involved. He asks who are those dangerous people
Mina: Kid had his hang-rider hidden in the luggage car. Conan had already figured that he'd have it there. Conan says now they are even and Kid doesn't owe him
Mina: Onto flashback. Conan had deduced that the old lady and her helper are Kid and his assistant. The maid is Kid whlie the old lady is the assistant.
Mina: Since the assistant can't change voice, Kid was speaking with close mouth while the assistant just mouthed the words, trying to hide the fact with the veil on the hat.
Mina: But since Conan is short and could see the mouth, it was all visible to him
Mina: The reason while Conan made the maid run down the hall was to confirm that the old lady will no longer able to "speak" without the maid around (since voice won't be disguised)
Mina: Conan also noted how the old lady was able to light fire to kiseru (the metal pipe) with no issue, whereas all the fire survivors were afraid of fire, so he figured she was someone else disguised
Mina: The reason Kid picked the old lady was because he could use the wheelchair to measure the length and width of the hallway. Kid comments that the real old lady is probably relaxing at home, believing
Mina: the false mail sent about change the departure date
Mina: Conan tells Kid that he should be grateful how Conan purposely overlooked the fact that they were trying to no get involved in the case by pretending they hadn't seen anything
Mina: Kid asks Conan if he's trying sell a fight, but Conan instead asks him to disguise into the woman in the video. The woman will be another room and tell him what to say through ear piece
Mina: Conan tells Kid to be careful since the place they'll force the woman to go will probably be rigged with explosives.
Mina: back to present. Kid says that Conan owes him for this.
Mina: Last page: Vermouth looks at Yukiko and commends her best casting. Ran gives back Sera her hat, commenting on how she found it in the hallway, though Sera is confused as to why in the hallway
Mina: Bourbon asks Vermouth to let him see files on Akai before his death. Vermouth agrees. Bourbon comments that he has to start his research from scratch
Mina: and that's it! Also there will be a break next week.
There will be a week break after 824 and a new case will begin.
