The way I see it this could be done in 2 ways, a slightly different version from what DTG do now (which is just make us pay for a couple of liveries that we should already have) or do an actual expansion. IDEA 1 so a better way than the DTG version of things would be Legends of the Gatwick express (not my idea I have just seen it on another post if your pfp is an EMT 158 and you said that you know who I'm talking to) This would give us 3 new trains: The class 442 Wessex electrics: This was the predecessor to the 387 on the Gatwick Express on this route, the 442 was built in the Derby Litchurch Lane works (now the place where Bombardier builds its trains) and entered service its design is based off of the MK 3 coaches used by HST's with improvements for a long distance commuter train made, it runs on 750v DC 3rd rail and has a top speed of 100mph however before it entered service it achieved the record for the fastest 3rd rail train in the world at a whopping 109mph (175 km/h) These trains operated with Gatwick Express from the early 2010s to 2016. The class 460 Juniper: This incredibly ugly looking train was built by Alstom at Washwood Heath between 1999 and 2001 it is in the same family of trains as the 334 and 458 (Juniper's) and entered service with Gatwick Express fully in 2005. When Gatwick Express decided to extend to Brighton the 8 460s were not enough so this is when 442s were introduced to run alongside each other in 2008, then soon after in 2009 these were withdrawn and replaced fully by 442s. The class 73: The class 73 Electro-Diesel Locomotive is a highly unique train as it has the capability to run on both 750v DC 3rd rail it also can run on diesel power (which it now does with Caledonian Sleeper north of Edinburgh) They entered service on freight lines in 1962 under the names E6001 and E6006 before then becoming 72/001 and 72/006 following their success some more were made with modifications most Notably the ability to run at 90mph rather than the previous 80 these Locos were designated as class 73/1s. In 1984 they Began to run on Gatwick express services from Victoria-Gatwick Airport hauling MK 2 coaches with a class 489 GLV on the end to negate the need for changing ends but it also provided the unit with extra power. Overall I think This would be a great Expansion pack with a doable amount of trains not to mention how all of them would e unique for DTG and would probably cost somewhere between the £10 or £15 mark. IDEA 2 This pack would do exactly what the name suggests and Expand the route but also add 1-2 new trains for the route expansions I have 2 ideas and 1 or both could be implemented the first and shortest one annoys me the most because it would be so easy and that would be Wivelsfield-Lewes, this would connect the routes of London Commuter and East Coastway it includes 2 new stations and they would be Plumpton and Cooksbridge and lasts for about 11 miles (this branch is entirely operated by Southern). The other option would be East Croydon-London Bridge with 9 new stations which are Norwood Junction, Anerley, Penge West, Sydenham, Forest Hill, Honor Oak Park, Brockley, New Cross Gate and London bridge this line runs for about 9 miles and then for the southern services to Victoria from London Bridge or for the new section to the game it would be Streatham Common to London Bridge call at Streatham, (not common just Streatham on its own) Tulse Hill, North Dulwich, East Dulwich, Peckham Rye, Queens Road Peckham, South Bermondsey and London Bridge, this part runs for about 3 miles. (this line is operated by Thameslink, Southern and Overground with AI Southeastern Trains at London Bridge) Now for the trains. The class 700: The class 700 dual voltage Multiple unit (can use 750v DC 3rd rail and 25kv AC 50Hz Overhead wires) was built by siemens as part of the Desiro City family from 2014-2018 and has a top speed of 100mph as this train is so highly requested you already know enough so I won't bore you but this should come with the 3 liveries aforementioned the Standard livery, the pride livery and the Thank You NHS livery for some nice differentiation. The class 455: The southern class 455 (now out of service with southern as of May 2022) would be a great addition and would fit with the time it was set when it was made, these units were made by BREL at their Holgate Road carriage works this type of train (455/8) was the oldest to be made with production beginning in 1982 and ending in 1984 these old trains provide a bit of a visual difference next to 377s as its something old and something new. Overall both these ideas would be great in TSW3 and I would even be happy to see both. FREE UPDATE Volumetric skies. new lighting update. Iris adaptation coming out of tunnels. 377/2 basically a 377/4 with a pantograph to be used for Milton Keynes services (I imagine the cab is different and maybe a different seating arrangement) this shouldn't be too hard and that's why it's in the free update section. GSM-R (so it's done fully and not like the 323 which isn't great but it's a step in the right direction) working CCTV camera screens in the cabs.
