Scenario Description:

On this crisp, winter morning, take 1L26 from Peterborough to Cambridge during its journey from Birmingham New Street to Stansted Airport.

You will have the pleasure of calling at Whittlesea and Manea which, for CrossCountry services, only happens a couple of times a day!

Enjoy the mix of modern Class 755 BMUs and freight movements along the Fens between Peterborough and Ely before traffic inevitably gets busy on the stretch between Ely and Cambridge.

The downloaded file (where you found this ReadMe) also contains a ‘Late Notices’ PDF and a Driver’s Diagram PDF. Please give these a read as they contain information regarding your stopping pattern, departure times and any Emergency Speed Restrictions (ESRs) – of which there are a few between Peterborough and Manea!

Scenario created using timings obtained from RealTime Trains data for Thursday 11th December 2025.

Scenario Specific Notes:

You may get a false red at the last signal before Waterbeach. A ‘force tab’ marker is in place to trigger the signal to step up. Please use the 9 key map to check the signal section ahead is clear to proceed.

Due to the use of several Enhancement Packs and dense AI traffic on this busy commuter route, this scenario can be quite demanding on your graphics settings – especially around Cambridge. If you experience lagging or OOM errors, please consider lowering your graphics settings. Unfortunately, these Enhancement Packs and AI traffic are necessary to create the most realistic scenario but as a trade-off this does mean they can be quite memory intensive.

This scenario has not been tested without: AP Signal Enhancement Pack, ATS AP Signal Enhancement Pack Patch, nor without the AP Sky and Weather Pack. Signals/weather may not behave as intended without these packs installed.
