Armstrong Powerhouse presents a Pro sound pack for the class 31 diesel locomotive.

How is a Pro sound pack different to a standard one?

If a sound pack is classed as being Pro, it means that most, if not all, of the sounds used have been recorded using state-of-the-art equipment at an especially organised recording session. This allows us to acquire the exact kind of sounds we require to create the best experience within the simulator. In the case of this pack, all sounds were recorded from 31206 at the Spa Valley Railway. As well as excellent audio quality, Pro packs include separate cab and exterior sounds because as anyone whose been in the cab of a locomotive knows, there is really quite a difference!

What is exactly featured?

Ticking spirax valve

Characteristic slow engine rev up

Subtle traction motor hum can be heard in the cab as you pick up speed

If the power handle is shut off sufficiently, the engine note will cut out as per reality with only the winding down turbocharger audible

User operable two-tone horn using the space-bar and 'B' key


Separate cab sounds

Bogie run sounds to give the sensation of movement

Brake release/application sounds

Brake rub

Brake squeal

Flange sound

Cab instrument sounds

Jointed track sounds (Co-Co 3-axles)

Realistic sound fading effects

Accurate volume levels. This means the quietest sounds are as quiet as they should be in relation to the loudest as per reality.

On top of the sounds, seven brand new high definition reskins are included which feature three different liveries for the class 31 and a bonus new livery for the class 37. These reskins use '4K' textures and as a result, give 16 times more detail than the originals. Please note, they will only work if you own the DTG BR Class 31 Freight:

DCR 31601

Ex-Fragonset 31459 'Cerberus'

Network Rail 31285, 31465 & 31602 'Driver Dave Green'

DRS 37419 'Carl Haviland'

During the installation process, this pack will be applied to the packs listed beneath the 'Essential Requirements' heading towards the bottom of this page. Please see below for a video demonstrating them:

If all of that wasn't enough, a massive four high quality scenarios are included, one for DTG GEML London to Ipswich & three for DTG West Coast Main Line North, to give those brand new high definition reskins a good run out. All scenarios are based on actual workings for these locomotives and feature realistic AI traffic from the relevant timetable of the year to ensure the most realistic experience available.

This add-on is supplied in download format only.
