The video discusses how a single number, PPH HPD (passengers per hour per direction), influences train design. It emphasizes the importance of optimizing designs to maximize passenger flow, considering factors like train height, door width, and the positioning of grab bars. The video also highlights how these design choices can affect comfort and efficiency on commuter trains.

There's a single number that can have an influence on every inch of a train's design.
It's called the PPH HPD: passengers per hour per direction.
It's essentially a measure of how many paying passengers will be on the train at a given moment in time.
Getting the design right to hit that target is crucial because the frequency of a commuter train isn't just limited by how many trains are on the line.
It's also affected by how quickly passengers get on and off.
The tiniest of adjustments to the train can impact passenger flow,
and that can make or break the economics of a train service.
If height isn't a constraint, you may think that double decker trains would help increase passenger flow.
It actually slows it down as passengers have to navigate stairs just to get to the doors.
The width of those doors is getting wider.
It's normally around 4 ft to allow two passengers to pass each other,
but on trains like New York MTA's new R211 T, the doors have been widened by 8 in.
The position of this bar can also have a huge impact.
If you keep them in the middle of the Tiu, people will stay stuck in the middle of the platform,
because they will try to grab the bar, which is a human reaction,
and they will create like a traffic jam.
By just moving the bar by 20 cm, you will orient the people on the right or on the left.
Designers then have to decide how much room to allocate for standing passengers versus seated ones.
The amount of space each standing passenger is allocated is a figure that varies depending on where the train is operating.
Usually, the number of people per square meter is between 3 to 6, depending on the cultures or the countries, and so on.
If you've ever felt slightly cramped on a commuter train, excuse me,
it could be because it was designed that way to maximize the number of paying passengers.
If you go for longitudinal seats or transversal seats, it will change everything.
Separately, these measures might not seem like much,
but added together, they can dramatically change the efficiency and comfort of a commuter train.
