How do you increase an engines pulling power. Im assuming its in the engine bin?

The easiest way to do this is to use TS Tools Asset Editor.
Select a loco in the asset editor.
Then select the option to edit rolling stock /edit locomotive physics.
Open the graphs option and you can put in new values in the tractive effort versus speed graph.
You can also alter the tractive effort v. throttle curve if you want.

Don't forget to backup a copy of the loco before editing.

There is a fair bit of information about pulling power or tractive effort in this thread on UK TS which may be of interest to some of you.
Be quick to extract what you want though because, unfortunately, UKTS may not ne around for much longer. (Edit: Official end of UKTS just announced for 31 August 2023.)

Did you intend to include a link? If so I'm afraid I can't see it.

Missing link now added.
The thread topic is about getting the physics right for a specific UK Diesel Multiple Unit. But the discussion includes general information which is applicable to single diesel locos. It even goes into refining the physics to account for air resistance (or drag) which I didn't know you could do in TSC.

As someone suggested somewhere, I've made sure that the UKTS forums have at least one snapshot on the Wayback Machine.

That thread should now be visible here:
