Calling Your Attacks: Returns this season along with the team cannon. The interesting thing is that the shot works differently depending on whatever the team imagines. Called (Insert Unique Effect Name) Rainbow Rush.
Color-Coded Characters: Subverted. The team is able to swap the Ressha in their ToQ Changer, resulting in a costume swap between members. For instance, Kagura is normally the Pink Ranger but can use Right's Ressha to become a Red Ranger instead. This may explain why they are identified by their number instead of color like they have been for decades now.
#1 also helps explain why the trope is normally in place, as Tokatti comments that with all the changes he can't tell who's who anymore.
Color Motif: The ToQger costumes are deliberately colorful and simple to compliment their rainbow motif. In contrast, the outfits for this season's baddies are much darker and highly intricate. Basically, simple and colorful = good guys. Complex and dark = bad guys. Pretty standard fare for Sentai.
Early-Bird Cameo: As per recent tradition, they appeared in the previous VS movie. They changed it, however, in that they appear after the ending to take down Neo-Geildon, who had just transformed into Neo-Messiah.
Eye Catch: Averted. As with the case of Gokaiger and Go-Busters, the show's logo appearing in the corner of the screen indicates a commercial break coming up.
Red Ressha + Blue Ressha + Yellow Ressha + Green Ressha + Pink Ressha = ToQ-Oh
Diesel Ressha + Tank Ressha + Car Carrier Ressha = Diesel-Oh
ToQ-Oh + Diesel-Oh = Cho ToQ-Oh
ToQ-Oh + Diesel-Oh + Build-Daioh = Cho Cho ToQ-Daioh
ToQ-Oh + Diesel-Oh + Build-Daioh + Hyper-Ressha-Teioh + All of the Support Ressha (including Shield and Drill, but excluding Scope and Energy) = ToQ-Rainbow
In the summer movie, Lion Ressha + Eagle Ressha + Panda Ressha + Alligator Ressha + Cat Ressha = SafariGaoh
Mecha Expansion Pack: Like previous Sentai mecha, there are an assortment of support Ressha that make alternate arms. Combinations with [X] Ressha are called [base mecha] [X] (or [X]-[Y] when it uses different ones on each arm).
Car Carrier Ressha: Shoots outvehicles as ammo - including other Ressha if ToQ-Oh is using a second one. As a separate car, it can launch the ToQgers to dangerous places via the cars, or act as a bridge.
Tank Ressha: This armored car is used as boxing gloves. As a separate car, it can refuel the Rainbow Line with special supercharged fuel.
The team also has some Ressha that they use with their weapons, but there's no sign of them being used with ToQ-Oh yet: Energy Ressha is ammo for the Renketsu Bazooka, and Scope Ressha is an accuracy add-on for the ToQ Blaster. Later down the line, the team will get another cannon weapon called the Dai Kaiten note Big Rotative Cannon that uses the team's Ressha as ammo, along with the Hyper Ressha. We also have some as-of-now unknown Ressha: Dump, Dozer, Mixer, Crane, Jet, Claw, Blizzard, and Ring.
"Super Sentai" Stance: The ToQgers do theirs lined up one in front of another (like train cars) rather than side-by-side, though in their first appearance in Kyoryuger vs. Go-Busters they did have one where they stood side-by-side.
Averted by the Transfer Changes, which are done in real-time.
Played with in the Kamen Rider Gaim crossover, where the team faces an Inves that's little more than a wild beast. It ignores the line and charges the ToQgers, only to get smacked around by the Ressha during the transformation.
Chekhov's Skill: Right tanking the Stove Shadow's coals without any reaction comes up again in #18, allowing him to con Ring Shadow into thinking the Restraining Bolt he put on Right wasn't even working.
Couch Gag: Each episode's opening has a different ToQger knocked over by an explosion in the background.
Clap Your Hands If You Believe: The team's powers come from their imagination. As in, imagine having super strength and being able to punch the bad guys through a wall.
Kagura also deserves special mention in this department. She'll often cower in fear upon being cornered by Mooks, but then she starts repeating to herself "I am strong... I am strong!" And then she'll start overpowering them like nobody's business.
This also applies to the Ressha as well. Cho-TokkyuOh was never in the original plans for the Ressha in design, so using the combo puts strain on the Ressha.
Dead All Along: The ToQgers themselves...are a subversion. Ticket actually said "good as dead", but they took it as literally dead and they started trying to solve it. As of #2, it's highly likely they aren't dead.
Death by Irony: The Rainbow Rush finisher defeats each monster in a manner that fits their crime somehow.
That detail just follows the general theme of the series considering that, in Japan, the arrival of a train at a station is announced that way. Ticket itself does that when arriving to Kettougaharanote Duel field station in #2
Mood Whiplash: #1 is generally a comedic episode, making us think its a lighter and softer season. Then at the end we learn that all the rangers are "as good as dead," which is the reason they were chosen. It was revealed by the monkey puppet for Pete's sake.
#26 has Akira introducing the team to bath house traditions, like drinking bottled milk coffee, which is actually a lesson from VRV Master in Gekisou Sentai Carranger.
Nice Job Breaking It, Hero: #26. The team carries out their own promotion for the bathhouse, but fail to raise enough money when Akira established his own discounts. Then the big fight begins, and takes a bad turn when Akira smacks Coin Shadow into the pool of darkness energy he was after the whole time. As per Rule of Three though, Coin Shadow cleaned up the darkness energy for our heroes as a result.
Numerological Motif: This time, the Rangers have numbers as their call sign instead of their colors.
Offscreen Moment of Awesome: In Station 21, Madame Noire squares off against Baron Nero in order to buy time for the To Q Gers to recover Grita. We see the two of them facing off with appropriate dramatic tension... and then they don't show up for the rest of the episode. The incident isn't brought up in the following episodes, either.
Their names are as follows Raito Asano, Tokashiki Katsu (Tokatti), Mio Natsume, Hikari Nonomura and Kagura Izumi.
Perception Filter: Fittingly anyone without enough imagination has trouble seeing the Rainbow and Shadow Lines. Everyday people can see the monster though.
Pink Means Feminine: This is actually subverted. Although The Chick gets pink as her primary color, none of the guys seem to mind being pink. In fact, Hikari willingly switched with Kagura as her weapon was lighter (though he left her with his weapon, which is too heavy for her to lift). Right winds up in pink as often as anyone else.
Powers as Programs: There's a power-swapping mechanic this year, allowing the ToQgers to switch their colors and personal weapons around while keeping their number.
Just Train Wrong: Any inaccuracies are justifed by the fact that these are magic imagination trains.
Rail Enthusiast: The show was made with them in mind; it even features train trivia in its ending sequence. Within the show, the first character to show such an appreciation for trains is surprisingly General Schwartz.
Railroad Baron: The members of the Shadow Line fit by virtue of trying to take over the Rainbow Line, but especially Baron Nero.
Steam Never Dies: Red Ressha - the most prominent train of the series - is a steam engine.
Rainbow Motif: The trains are part of the "Rainbow Line" and run on rainbow tracks. The way ToQ-Oh is built, with the component trains making five vertical stripes, even makes it look like a walking rainbow.
Spell My Name with an S: The official romanization of the word for "express line" is "ToQ" instead of the more common "Tokkyu". But as is often the case, it's not consistent; the official show website, for instance, spells the name of the robot as "Tokyuoh".
