One month prior to the "Pure Trance" single release, many of the same core elements were also used in ambient form during the tracks "Wichita Lineman was a Song I Once Heard" and "Trancentral Lost in My Mind" on the KLF's third album, Chill Out (1990).

[1] The "Pure Trance" version of "Last Train to Trancentral" is a minimalist ambient house reworking of "Go to Sleep", stripped of the female vocals and all but one line ("And from somewhere, I hear") of The KLF co-founder Bill Drummond's narration.

[2][3] Indeed, upon its release, "Last Train to Trancentral (Pure Trance version)" was not easily categorised, with Record Mirror claiming that "it isn't a dance track".

Featuring vocals by reggae musician Black Steel and a rap by Ricardo Da Force, this house reworking follows a conventional song structure, with a rhythm that mimics the sound of a train in motion along its tracks.

Entitled "Last Train to Trancentral (Live from the Lost Continent)", this was the third and final instalment of The KLF's so-called "Stadium House Trilogy" of singles, following up "What Time Is Love?"

Larry Flick from Billboard commented, "Matching the brilliantly kooky, Tammy Wynette-fronted "Justified & Ancient" is a tall order, but the mysterious production team succeeds by sticking to an enticing combo of odd samples, funky beats, and anthemic chorus chants.

"[5] A reviewer from Record Mirror noted the "ethereal atmospherics" of the "Pure Trance" version,[6] but the single was poorly received by Melody Maker, who interpreted it as a joke: "'Look how mischievous we are', the fatheads giggle!

"[8] In comparing "Last Train to Trancentral (Live from the Lost Continent)" to the KLF single "Justified and Ancient", Simon Williams from NME called the former a "sheer frantic rush".

[10] Caroline Sullivan from Smash Hits wrote about the song, ""Last Train" follows the "3am Eternal" formula: a live feel, huge, swirlaway beat and insanely catchy chorus.

"[12] In 1999, Tom Ewing of Freaky Trigger ranked the song at number 42 in his list of the "Top 100 Singles of the 90s", saying "No band understood the possibilities for mass lunacy contained in the new music as well as did the KLF.

[...] Read a copy of The Manual, Bill Drummond and Jimmy Cauty’s pricelessly cynical dissection of the process needed to have a No.1 hit, and the depth of their understanding begins to show through.

The KLF did to house what Jim Steinman did to rock – they turned it into a thing of tottering grand opera absurdity, pushed the excitement in the music to hysteria, traded content for ever-huger gesture.

Describing his journey, rapper Ricardo Da Force says "A brand new day is dawning, a light that will anoint me, a sign from the subconscious, an angel sent to guide me, the searchin' will be over, the call will now be gentle...".

The kitchen is heated by means of leaving the three functioning gas rings on at full blast until the fumes make us all feel stoned, there's a bag of litter in the hallway that everybody trips over going in and out of the place, as well as a very old motorbike... And, pinned just above a working top cluttered with chipped mugs is a letter from a five-year-old fan, featuring a crayon drawing of the band.

Friends recall the good times, at the height of the acid-rave scene, when the KLF would throw 'really brilliant fuck-off parties', sometimes lasting all weekend, with a fairly relaxed attitude to uninvited house guests".

Additional contributors on these versions include: "Last Train to Trancentral (Pure Trance remix)" was aired as a UK 12" single in March 1990, in an issue limited to 2000 copies.
