Only Connect Wall #1

Hosted by Victoria Coren Mitchell, Only Connect is a British quiz show known for its fiendishly difficult questions. This quiz has adapted Round 3, with slight changes to the rules to be more JetPunk-friendly (see below). Can you find the connections?
First solve the wall off-screen.
When you think you have a solution, sort the items in each group in alphabetical order.
Now using the first entry of each group, sort the groups into alphabetical order.
Input the groups into the screen in that order. Example given in comments for further clarification.

Using S10 E17 as an example, our groups are:

Teal, Merganser, Eider, Wigeon (types of duck)

Flying Scotsman, Rocket, Puffing Billy, Mallard (famous trains)

Orient Express, Mesopotamia, Styles, The Nile (Poirot locations)

Malik, Tomlinson, Horan, Payne (1D members)

Sorting the items alphabetically, we get:

Eider, Merganser, Teal, Wigeon

Flying Scotsman, Mallard, Puffing Billy, Rocket

Mesopotamia, Orient Express, Styles, The Nile

Horan, Malik, Payne, Tomlinson

We should therefore input the groups as follows:

Eider, etc.

Flying Scotsman, etc.

Horan, etc.

Mesopotamia, etc.
