Perth, Australia has been running electric commuter trains for some 23 years. There are some 48 sets of the 'A' series. These 48 sets of 2 rail cars are numbered 201/301 up to 248/348 ... so commonly known as 01 to 48. The sets can run as 2 cars or 4 cars, so for example set 23 can be linked up to set 19 in a 4 set configuration. The total 23 + 19 = 42 has no real use .... except to raise the question here ....
What are the most popular values of train set numbers when up to 2 sets are combined?
And for the those with attention to detail in the question, any set of 2 cars can run by itself, so from the outset, all numbers from 1 to 48 have one count towards their popularity from the start. Bottom left - 201 of the 201/301 set or commonly known as 01. Bottom right - a set of 4 rail cars (2 sets of 2).
