Hi again Paul, I forgot to add to my last post so i will add it here. If you are making activitys using a batch of the same stock. Can i advise you on some tips for this ? From my experience in making activitys using BR stock how about having a total of around 10-15 downloads for the activitys for example if you make a loco-hauled passenger activity for the S&C or the FUDE route (i quoted these routes as examples) using a class 47 and some Mk1 coaches for the player train and if it is on a busy route - you could have about 5 or 6 BR blue loco's, 1 HST 125 set and for the AI dmu's you could have the BR Blue class 101 and BR Blue 117 for the local trains and many types of wagons for the freight train traffic you could use also in a freight activity too. Also here is a sample list using 10 downloads for an activity

.
Diesel Loco's
Class 25 in BR Blue (To be truthful i don't remember much about the class 25 as it did not operate in my area to my knowledge).
Class 46035 in BR Blue These locos are usually coupled to BR Mk1 coaches when working passenger services and mixed freight work when used on freight services too. (You can use van wagons, hoppers, and even container wagons for the particular train)
Class 37 in BR Blue - My favorite loco of the 80's (This loco was used on multiple duties so you could use just about anything with this classic loco

Class 43 HST Blue/White (High Speed Passenger duties

)
Class 47 BR Blue (These are oftern used on Cross Country duties even back in the 80's and Intermodal Freight work as well as the odd Coal Hopper workings too)
Class 56 BR Large Logo (This could be used on VEA van consist's and HAA Hopper trains as well as some Intermodal duties)
BR Mk1 coaches, If you wanted to keep downloads to a minimum - you could the ones that come with the class 50 update pack.
BR Railfreight VEA vans - these wagons are used to deliver many types of goods such as fish, funiture and other light goods from the 70's early 80's era.
BR HAA/HDA hopper waggons (These are hauled by mainly class 56's before the class 58 entered service in 1983).
BR Container Wagons (Hauled by class 37's ,47's and 56's).
Class 101 and 117 (Both of these dmus were a common sight on local trains during the early to mid 80's - I also remember the WM logo's on our examples in Birmingham)
You will probably want to increase the decrease the amount of downloads or change the trains above in my sample list. I know the BR Mk1 coaches in the update are not the best - but the reason i suggested these is because those on dial-up 56k will have fewer items to download. But if you wanted to - you could make a "Lite Version - Minimal download" and a "Full Version" that uses more downloaded stock. But i will leave those ideas up to you to decide

. Whatever trains and stock you use i will be looking forward to playing on your activitys in the near future

. All the best of luck with them and remember to save regularly because MSTS has servere mood swings

. And you wouldn't want to lose valuable work that you have spent hours on hours and then MSTS crys "Let's go home !" with the "ultra-annoying" send/don't send message and then having to start over again

.
Hope this helps
Cheers
Yuri
