- "Our whole lives changed ten years ago when the evil Shadow Line appeared, casting our entire hometown in darkness. Fortunately, my siblings & I were rescued & taken to the Rainbow Line, where we were raised by our Uncle Herbert. Ten years later, we have returned to our hometown, & we're determined to save everyone we love from the Shadow Line. Together, we are Power Rangers Train Quantum Guardians!"
- —Russell narrating
Only those with a great Imagination can see the mystical railway known as the Rainbow Line, on which run massive trains known as Trainzords are driven by five young Power Rangers known as the Train Quantum Guardians. While it is their mission to save towns from the evil forces of the Shadow Line who are using the residents' fear & sadness to establish their railway to enable the coming of their leader Emperor Zedd, whose intention is to consume light to plunge the world into darkness, the five Train Quantum Guardians are also siblings, the Mervilles, who also fight to recover the memories of their parents & hometown after it was consumed by the Shadow Line's evil years ago. After being joined by a former Shadow Line member named Zaram who now goes by the name of Aaron as their sixth member, the original Train Quantum Guardians regain their memories of their hometown & discover that it is completely consumed within the Shadow Line's railroad. The Train Quantum Guardians begin a campaign to free these "Shadow Towns" from their Shadow Creep Keepers in an attempt to recover their memories & save their parents & friends, while Emperor Zedd must deal with some opposition among his subjects.

When the evil Shadow Line begins to use their evil train, the Shadow Liner, to kidnap children, Russell mysteriously finds himself amongst those nearly captured.

After learning from their uncle what happened to them & their parents ten years ago, Russell is inspired to help protect the children with his siblings.

- TQG features the first official Orange Ranger.
- This may be the first season since Power Rangers Super Megaforce to feature the original Red-Blue-Green-Yellow-Pink main team formation.
- This may be the second time a Power Rangers season has adapted the Sentai out of order, as ToQger was skipped over initially. The first was Power Rangers Beast Morphers.
- This may also be the first season since Power Rangers Lightspeed Rescue where the Rangers' suits have white gloves & boots as part of their uniforms.
- Just like Dino (Super)Charge 's similarities to Jungle Fury, TQG also shares many similarities with RPM. This trend would continue in the next series.
- The heroes are vehicle-themed.
- RPM's final set of zords are trains, which is the main motif of TQG.
- The villains are from other dimensions & try to terraform Earth. (Venjix Computer Network & Shadow Line).
- Both teams have 7 Rangers with 5 Males & 2 Females.
- Both feature the #3 female Yellows (Train Quantum Guardian Ranger 3 & Ranger Operator Series Yellow) which was used for the special-mission themed heroes 4 years later (Yellow Shade Ranger).
- Both have some heroes in the core team share the same weapon.
- Sword: Train Quantum Guardian Ranger 1 (Rail Slasher) & Ranger Operator Series Red (Street Saber)
- Trigger: Train Quantum Guardian Ranger 2 (Platform Blaster) & Ranger Operator Series Blue (Turbo Cannon)
- Ax: Train Quantum Guardian Ranger 4 (Tunnel Axe) & Ranger Operator Series Green (Turbo Axe)
- Coincidentally, all of them are male Rangers with the same color & number (Red, Blue, Green & numbers 1, 2, 4 respectively).
- Each member of both teams has seemingly long ranger names that can be shortened to just "Ranger ______". This would later be used by the Justice Rangers four years later.
