I need help creating freight scenario

[Nippur]

Hello, I will try to explain the best I can (English not my primary language). I'm creating a freight scenario, I made freight and passengers scenarios before but I'm having a specific problem with this.

I want the freight train (player) stops at a signal after a curve, before diverting to the main line, so 3 express passenger trains can pass in the same direction before the freight train gets a clear signal.
I did this before, entering a loop and the passenger trains pass without a problem, then I got a green light and continue.

I managed to do it for 2 passenger trains, the third waits and I get a green light. It's OK but not realistic, there is a huge gap between this point and the next loop I selected to divert, so again other 2 trains behind can pass.
I was thinking that maybe the AI calculates I will go faster than 60mph.
The freight train is a Class 56, 80mph top speed, so a performance of 75% should be 60mph.

Maybe someone can help me with this.

NOTE: I already have the correct train types: "slow speed freight" and "express passenger" for the other 3 trains.

Wow, you give a good explanation. Possibly the the number of track sections the dispatchter takes into account is limitid, so it doesn't see the third train. You may try to place the passenger trains all in the same block initially. I'm not sure this works well, sometimes you simply cannot get it to work properly and you may need to do consessions to what you want to achieve. Otherwise, It hink you did the right things to make it work and it looks you are well skilled in creating complex scenario's. Wish you luck in solving the issue.

Try giving the 3 passenger trains a much higher priority from the list. Make them "International or Empty Stock" that should help. And do not have the timings for the 3 passengers set too far apart say; P1 10.00.00, P2 10.01.30, P3 10.03.00.

One other point. As far as I know the default "75%" has nothing to do with the top speed of the loco or train. It is to do with AI's and the track speed. If left at 75% then TS calculates the speed of the AI. So if track speed is 100 mph then the AI should run at 75 mph and so on. Increase or decrease that percentage and they should run faster or slower.

Hope this helps.

Thank you, changing the third passenger train type to international fix this.

This is JT Western Mainlines route, in the image I posted before you can see Didcot Parkway. Between Didcot Parkway and Swindon the freight train will divert two more times to let passenger trains pass.
I already make the next stop, 2 more passenger trains pass. Now I have to make the third stop in a loop just before Swindon station. And another divert between Swindon and Bristol Parkway .
