Which services, currently booked for pairs of 153s, are going to be 2 car 197s in future?
Crewe shuttles? Plus the long list of services where 153s regularly deputise.
The point was that even a pair of PRMed 153s offers more seats/toilets/luggage space/bike spaces than a 2 car 197. Here's a comparison (figures off the top of my head, corrections and missing data gratefully received)
| Unit | Seats | Toilets | Luggage spaces | Bike spaces |
| 150 | 128 | 1 | 0 | 4 |
| 153/0*2 | 118 | 2 | 2 (and they're pretty big) | 4 |
| 158 | 128 | 2 | 4 | 2 |
| 175/0 | 125 (not counting tip-ups) | 2 | 4 | 2 |
| 197/0 | 116 | 1 | 2 | 2 |
So when services between Birmingham and Holyhead are proposed to continue to be two coaches between Shrewsbury and Holyhead, ditto for other busy flows such as Machynlleth-Pwllheli (think Barmouth during the summer), this hardly ranks as an improvement in capacity on routes which have been suffering from severe overcrowding for 15 years.
What about longer sets? I've included the former Manchester Mk3 set to show the sort of capacity that used to be available (and which was well filled for the majority of the day, 1D34 used to leave Warrington basically full).
| 175/1 | 200ish | 3 | 8 | 2 |
| 67+4*Mk3+DVT | 280 | 8 | 8 (equiv of 16 DMU racks) | 5 |
| 67+4*Mk4+DVT | 223 | 4 | 7 | 5 |
| 67+5*Mk4+DVT | 291 | 5 | 9 (can't remember size) | 5 |
| 197/1 | 188/174 | 2 | 2/3 | 4 |
Manchester - North Wales services will continue to be three coaches between Chester and North Wales as at present, with only a few peak trains to Manchester strengthened. These services are rammed as things stand. If you can get a standing place, you're lucky, many people get left behind. Imagine that you've been on holiday to Prestatyn (no, me neither). You've just left your holiday camp on the Friday and walk to the station with your partner, three kids (the youngest in a buggy) and all of your luggage. Everyone else from several other holiday camps is following you. You get to the station to see the platform is packed, a train pulls in but not one of you can get on - everyone from the holiday camps at Abergele is already on, plus a handful from Rhyl who just about squeezed on, leaving the rest behind. You sit on your suitcases on the platform for roughly two hours and the 12:43 to Cardiff pulls in. Amazingly it is actually LHCS today (nothing failed on Canton this morning) so you can actually squeeze on. But you didn't want to go to Cardiff, you are going home to Manchester/Preston/Telford/wherever. So if you do give up and take this train just to make some progress, you will have to change in Chester or Shrewsbury as applicable.
Under the current proposals, train lengths for most flows along the NWC will remain as they already were. The only changes are that Cardiff services may be longer (still no confirmation of the length of non-LHCS services), and that there's a new service to Liverpool - but that's only two carriages so will already be full when it departs from Llandudno.
Of course most pairs of 153 contain a single PRM and the second 153 does not have the toilet (or at least in my experience).
If there's a PRM-lite one in the formation then it will have even more seats so outstrips the 2 car 197.
