Bus Wash and Train Wash Systems: How do Trains and Buses Keep Clean?

If you’ve ever caught a public bus or train, you would have noticed the number of people who are constantly getting on and off—bringing their dirt, germs, and spilling sticky drinks. In the rainy season, mud gets trampled all over the floor and cold and flu particles fly all around—making frequent cleaning of paramount importance for the sake of public health and safety.

So, how often do bus wash and train wash routines take place? And how thoroughly are they actually cleaned?

Cleaning on a Schedule

As it turns out, hundreds of cleaners are employed across the country to keep our public transportation vehicles clean so that passengers can have a safer and more pleasant journey. A clean transportation system increases users’ confidence and comfort and makes travelers more likely to use public transport. This makes cleaning a top priority!

Every night, buses and trains that have finished their scheduled trips are stored, cleaned, and prepared for the next day. These late-night and early-morning hours are used to keep the vehicles up and running. Less frequent, deeper cleans remove the build-up of dirt, grime, and bacteria to maintain a healthy environment.

The Bus Wash Schedule

After their final run, buses are taken back to the garage where they are swept out and put through a pressurized bus wash. Vandalism or damage is noted, and if this can’t be fixed there and then, the bus is set aside until the needed repairs can be done. Buses are refueled overnight to make sure they are ready for the next day.

Every 45 days or so, buses undergo a more thorough bus wash. The ceiling, windows, handles, and grab rails are all washed with detergents and disinfectants and the floor is mopped thoroughly. Upholstered seats are cleaned with a carpet extractor and damaged pieces of furniture are repaired or replaced. Deodorizers may also be used to freshen up the smell inside the vehicle. This is always a good telltale sign that the bus has just had its scheduled clean!

The Train Wash Schedule

Trains have a similar routine to buses. Each night, they are taken back to the end of their lines, swept through, and driven through a train wash. Windscreen fluid is topped up and the sand boxes are refilled. Many people aren’t aware of this, but sand is released as needed to help with traction on the rails. Finally, the trains are positioned ready to set off on their first scheduled trips for the next day.

Every 6,000 miles, or roughly once a month, trains are cleaned thoroughly—just like in the 45-day bus wash. The windows and surfaces are cleaned with detergents and disinfectants and the floor is vacuumed and mopped. The seats are cleaned with an upholstery extractor and damaged seats and seat backs are replaced. It takes about eight hours for one cleaner to go through and clean an entire train.

Special Cleaners for Special Vehicles

Traditionally, all vehicles had to be washed by hand—a time-consuming and inefficient process that used a lot of water. Nowadays, transit and fleet vehicles are typically washed in drive-through washers in a process that is streamlined, fast, and more environmentally friendly. Let’s take a look at how drive-through washers for buses and trains are designed and how they work.

Drive-Through Bus Wash Design

An automated bus wash is similar to a car wash system but larger. These tunnels generally have between two and six vertical brushes to clean the sides and a horizontal brush to clean the front and back. Water squirts from two rinsing arches for the rinse cycle and there is a technical tower or board for wash-cycle control as needed.

Some drive-through washers are closed at the top to fit a specific vehicle size, whereas others are open and can accommodate even the largest coaches and trucks. An entire bus can be double-washed in one of these systems in as little time as eight minutes, or sometimes even less!

Drive-Through Train Wash Systems

Drive-through train washers are somewhat larger than bus wash systems—mainly due to their length and the overhead contact line required by electric trains to move. The bays are designed for a specific model of train to accommodate its powering needs (electric or diesel), its total length, its height off the ground, and the specific shape of the train front. Train fronts range from almost flat to aerodynamic models with a pointed nose.

The process used to wash a train follows the standard cycles used in a car or bus wash:

  1. A rinse cycle (usually with recycled water) to remove dirt, mud, and other particles
  2. A detergent cycle with brushes to cut through grease and grime
  3. Another rinse cycle to remove the detergent
  4. A drying cycle in cold countries to prevent the water from freezing on the train

In the first two stages, the train is still moving forward. After detergent is applied, the train comes to a complete stop and the front of the train is washed while the product is allowed to work on the body. For the last rinse cycle, the train moves at about 1.5-3 mph until it comes all the way through the bay.

Whereas a bus wash only needs a firm surface underneath the wheels, a train wash needs to have a railway track running through the entire bay to allow the train to move.

Keeping the Tracks in Shape

While train washes are helpful, the actual train isn’t the only part of the rail system that needs cleaning and maintenance. The railway track and rocky cushioning material that supports this track (called “ballast”) need to be cleaned too. This special job is performed by a fully-automated machine called a “ballast cleaner” that goes along the track, lifting up the rails and cleaning the ballast in a conveyor-belt system before re-placing and re-securing the rails.

The massive ballast-cleaning machine makes it unnecessary to hire the thousands of rail workers that were required to lay many of these tracks in the first place. It keeps the railway system free from large debris that could jeopardize the train and passengers’ safety.

How You Can Help Keep Buses and Trains Clean

With all the work that transportation companies put into their bus wash and train wash schedules, it is vital that each passenger do their part to help keep buses and trains clean. This is what you can do to help:

  • Refrain from eating and drinking during your journey (exception for water bottles)
  • Throw your trash in designated trash receptacles or take it with you
  • Cover your mouth with a tissue to sneeze or cough, and throw the tissue into the trash
  • Avoid touching your face as much as possible
  • Wash your hands before and after traveling
  • Carry an antibacterial gel to use after traveling and before handling food
  • Let the driver or station attendant know if you see graffiti, vandalism, or other damage on the vehicle that needs to be repaired

With each person taking responsibility, public transportation can be a cleaner, safer system for all!
