How to advertise on subway vehicles? From chartering a car to body stickers, understand all the gameplay in one article

When you walk into a subway car, the brand images covering the entire train, creative stickers on the windows, and interactive designs on the pull tab all belong to the category of subway body advertising. Unlike platform lightboxes, vehicle advertising is a mobile, enclosed, and zero distance media that can repeatedly reach every passenger with brand information within a 30 minute commuting time.

But for brand owners who are new to subway advertising, they often feel confused when faced with professional terms such as "private car", "car body stickers", "car posters", etc.: What are the forms of subway car advertising? How much is it? How to invest effectively?

This article will systematically review all aspects of subway vehicle advertising, from core forms to real-life cases, providing a complete introductory guide.

1、 What is subway car advertising?
Subway body advertising is a broad concept that refers to advertising media placed inside or outside the train body. According to different locations, it can be divided into two categories:

Train external advertising: including body stickers, window stickers, and other forms that cover the exterior surface of the train and are seen by platform passengers when the train enters and exits the station.

Train interior advertising: known in the industry as "interior carriage" or "themed carriage", covering signs, handles, door stickers, window stickers, seat side stickers, roof stickers, floor stickers, etc. inside the carriage, forming an immersive brand space.

In a broad sense, subway advertising can be divided into two main parts: subway station advertising and train advertising; Train advertising includes various forms such as in car and body advertising.

2、 Why choose subway car advertising? Four core advantages
1. Compulsory access to enclosed spaces
Subway trains are typical "information islands". The average stay time of passengers in the carriage is about 30 minutes, and the mobile phone signal may be poor, with less external information interference. During this period, vehicle advertising became the visual focus that could not be skipped or ignored, achieving true 'forced reach'.

2. Close range and long-term exposure
Unlike long-distance viewing of platform lightboxes, vehicle advertising comes into close contact with passengers. The handle advertisement is less than 50 centimeters away from the line of sight, and the car sign is right next to the seat, making it impossible to avoid. This close range exposure allows brand information to be deeply conveyed.

3. Immersive brand experience
The advertisement for the internal charter of the entire train can create a brand exclusive space for the carriages. From billboards and handles to door and window stickers, and even the roof and floor, it covers all aspects, making passengers feel like they are in the brand world. The Beidahuang themed carriage of Harbin Metro Line 2 achieves immersive brand promotion through a single six carriage internal charter.

4. High frequency and stable population
Most subway passengers are commuters who take the same route every morning and evening. This means that the same group of passengers will repeatedly see advertisements for the same train within a month, forming a profound brand memory.

3、 The main forms of subway vehicle advertising
3.1 External Advertising on Trains
Car body sticker advertisement: a film advertisement covering the outer surface of a train. Including forms such as full body, semi body, and side advertising. When the train stops at the platform, passengers on the platform can clearly see it.

Car window sticker: a semi transparent film covering the train windows, which does not affect passengers' ability to look out and allows platform passengers to see advertising images.

3.2 Internal advertising of trains (internal charter)
This is the most core and comprehensive form of subway vehicle advertising. The "Subway Theme Car Advertising Project" launched by Beidahuang Food Group on Harbin Metro Line 2 in January 2026 is a typical case of in car transportation, covering the complete packaging of six single car carriages.

Internal charter usually includes the following locations:

Carriage sign: A large-sized image on both sides of the carriage wall, which is the main point of the inner carriage, and passengers have their line of sight facing when sitting or standing.

Handle advertisement: Advertisements are placed on the handles hanging on the top of the carriage, which passengers must reach and have a very high reach rate. A brand once made a three-dimensional product model of the handle, which caused passengers to take photos and check in, and unexpectedly gained popularity on social media.

Car door sticker: an advertisement on the inside of the carriage door that naturally enters the line of sight when opening or closing the door.

Car window sticker: A film advertisement on the car window glass, which can be designed in a semi transparent or transparent area to ensure natural lighting without affecting viewing.

Car seat side sticker: an advertisement on the side of the seat that passengers can watch up close when seated.

Roof stickers/floor stickers: Advertisements on the ceiling and floor, which are rare but can create a complete immersion.

3.3 Digital media inside the carriage
Including LCD screens, LED screens, etc. inside the carriage. The Guangdong Hong Kong Macao Greater Bay Area Lantern Festival advertising project, tendered by the Hong Kong MTR in January 2026, involves the placement of dynamic LED screen advertisements on train carriages of the East Rail Line, Tuen Ma Line, Kwun Tong Line, and other lines. A total of 5958 screens are displayed 12 times a day for 10 seconds each time, with a budget of 326700 yuan.

4、 Real advertising cases and price references
Case 1: Beidahuang Food Group Harbin Subway Charter (2026)
Beidahuang Food Group launched a subway themed carriage advertising project on Harbin Metro Line 2, featuring a single row of six carriages, with a transaction amount of 849500 yuan.

Service content: Within the agreed period of the contract, display 6 carriages in a single row on Harbin Metro Line 2 at the agreed time as requested by the purchaser, display our advertising image, and expand brand promotion.

Price interpretation: 849500 yuan is the complete interior charter price for a single 6-carriage train, including media publishing fees and publication services for all locations. This is the publicly available transaction price for government procurement, which can serve as a reference benchmark for similar advertising.

Case 2: Guangdong Hong Kong Macao Greater Bay Area Lantern Festival Hong Kong Metro Launch (2026)
The Guangdong Hong Kong Macao Greater Bay Area Lantern Festival will place dynamic LED screen advertisements on train carriages in the Hong Kong subway, covering a total of 5958 screens on the East Rail Line, Tuen Ma Line, Kwun Tong Line, Hong Kong Island Line, and South Island Line. The broadcast frequency is 12 times a day, each time lasting 10 seconds, with a duration of 4 weeks and a budget of 326700 yuan.

Price interpretation: 326700 yuan is a packaged price that includes all costs such as material production, advertising space, installation, debugging, labor, taxes, etc. The average weekly cost per screen is about 13.7 yuan. This large-scale advertising model has extremely high cost-effectiveness.

Case Three: Voice Naming of Chongqing Rail Trains (2026)
Voice naming advertisement for Chongqing Metro Line 3, Line 6, and Circle Line trains, priced at 48000 yuan per vehicle per month. Using train carriages as carriers and voice as communication channels, intensive exposure is carried out inside the rail carriages, including naming voice, in car arrival voice, platform departure guidance voice, etc.

Price interpretation: This is a "pure sound" form of vehicle advertising. Although it does not have visuals, it can still achieve brand communication effects through high-frequency voice contact.

5、 Five step practical process for subway vehicle advertising placement
Step 1: Clarify goals and audience
Before contacting any supplier, ask yourself three questions:

What is my core goal? (Brand exposure? New product promotion? Event traffic?)

Who is my target audience? (Young white-collar workers? Family users? Business people?)

Where is my core market? (Covering the whole city? Deeply cultivating a certain route?)

Subway advertising placement is not simply about spending money, but should comprehensively consider factors such as budget, brand declaration, product conversion, industry attributes, and consumer classification.

Step 2: Choose the appropriate form
Choose a matching advertising format based on budget and objectives:

Adequate budget (over 800000 yuan): Consider chartering a themed car to create an immersive brand experience

Medium budget (300000 to 500000): Consider digital media or advertising on the car body inside the carriage

Limited budget (within 100000 yuan): Consider using handle ads or in car billboards, or selecting fragmented advertising on specific routes

Generally, fast-moving consumer goods are suitable for train media during promotional periods, with low cost and high conversion rate; Durable goods or high-value products are more suitable for station hall or platform advertising.

Step 3: Filter the target route
The choice of route directly determines the advertising effect. Need to screen based on target audience:

Reaching young white-collar workers: choosing routes that pass through CBD and technology parks

Reaching household users: choosing routes that cover large residential communities

Reaching the business community: choosing routes that connect transportation hubs and core business districts

Step 4: Creative Design and Production
The creativity of subway advertising has its unique requirements:

Design principles for internal charter vehicles:

Visual unity: The entire train has a unified style, creating an immersive experience

Point linkage: The content of signage, handles, door stickers, and other points echoes, forming a complete narrative

Interactive design: Reserve a scanning entrance to guide passengers from exposure to interaction

The Three Second Rule: In a noisy commuting environment, passengers' attention must be captured within 3 seconds. The brand logo should be large, the core information should be short, and the visual impact should be strong.

Creative production cycle: High quality in-house car design and production usually takes 2-4 weeks, and the budget needs to be separately reserved.

Step 5: Publication Execution and Effect Tracking
Publication monitoring: Require service providers to provide photos or videos of the publication to ensure compliance with the agreement.

Effect tracking:

Exposure data: Calculated based on line passenger flow to cover the number of people

Interactive data: Set up exclusive QR codes or discount codes to track consultation volume

Search Index: Monitor the Baidu Index changes of brand keywords during the advertising period

6、 Common Misconceptions and Avoiding Pits Guide
Misconception 1: Confusing "in car rental" and "in car posters"
Internal charter is a comprehensive packaging of the entire carriage, including signs, handles, door stickers, window stickers, and all other points, creating an immersive experience; The posters inside the car may only be a few separate advertising spaces inside the carriage. The price and effect are vastly different, so it is important to confirm which points are included before signing the contract.

Misconception 2: Only focus on price, not the value of the route
The passenger flow on the same route varies greatly in different sections. The passenger flow at core transfer stations may be several times that of regular stations. Be sure to confirm the specific passenger flow data of the delivery route.

Misconception 3: Creative use of outdoor designer brands
Directly using the static images of outdoor big brands on the handle will inevitably have a discounted effect. Creativity must be customized for close range and long-term viewing of train car scenes.

Misconception 4: Ignoring the approval cycle
The content review of subway advertisements is strict, and it usually takes 2-4 weeks from creative submission to actual publication. If rushing to market, it is necessary to plan ahead.

Misconception 5: Collaborating with unqualified intermediaries
It is necessary to verify the qualifications of the agent to ensure that they have the legal operating rights of the subway media. The case of Beidahuang shows that the successful supplier is Harbin Xintu Culture Media Co., Ltd. Professional platforms such as Tianci Media can provide one-stop full process services, from demand analysis to effect tracking, to ensure smooth delivery.
