Anyone familiar with, or travels through any NW region I would imagine has seen these units; they span large parts of the Northern region to some degree. Between the two classes, around 100 units have been built, and the only external difference between the two classes are that the 331 is electric, and the 195 is a DMU. Without these units in TS2020, large parts of the Northern operated region is effectively stuck in mid 2019 when the region's multiple units were predominantly class 319, 323 and a mixture of diesel stock (150,156,158etc). Without these units, many future developments of large parts of the region will sadly be lacking any realism. The region's 142 have all but gone now, and the older Sprinter class units are disappearing too. Northern operate a huge region of the UK network: Cumbria, Lancashire, the Fylde Coast, down into Southport/Merseyside, Manchester across to the Yorkshire coast (Hull, Scarborough etc), and as far as up to the North East... and as far south as Nottingham. A lack of Civity unit will have far reaching impact for future route development across a wide part of the UK as these units can be seen across a wide range of this map. In Yorkshire for example, 331s are replacing older 321 and 322 units. They have replaced 319s on the Blackpool to Manchester Airport route, and will begin to replace 319s on the Liverpool Lime St services. In fact, the Liverpool Lime Street to Crewe via Manchester Airport is the longest route on the Northern operated map, and will be predominantly Civity units soon. Surplus 331s will operate all electrified commuter services between Hazel Grove and Blackpool North, Manchester and Glossop/Hadfield and Manchester and Stoke-on-Trent. Introductions on these lines are to begin towards the end of 2020. Yes, it's an ugly Spanish built piece of multiple unit mediocrity... but it's actually quite important for many future routes and scenarios.
