Puzzle Location: Footpath by the river (Hans Lipski)

There are four railways running parallel to each other, and each has four stations.

It costs £2 to travel through unlimited stations on one railway line.

It costs £1 per station to travel on a bus that links vertically adjacent stations on different railway lines.

What is the cheapest possible route from the station at the bottom-left, taking in all three of the red stations along the way?

There is no other possible mode of transport.

Hint 1

First, find the shortest route through all three red stations.

Hint 2

Continuing on from hint one...

The shortest route passes through eight stations, not including the departure station.

Hint 3

Continuing on from hint two...

The first stop is the station at the bottom-right, so take the direct route there.

Super Hint

Continuing on from hint three...

You can just pass through the red stations; there is no need to stop at them.

Be careful when you are calculating the fare.
