Dear WMR,
No, get those 153s out of storage and run those to supplement your services.
If, however, the DfT allows us to place an order for brand new FLIRTS to replace our entire Regional fleet (which would probably enter service before your CAF 196s do!), you can have our 170s. You can have our 158s too if you’re really worried about having sufficient rolling stock.
Lots of love,
EMR
WMR then gets a letter from the DfT…
Dear WMR,
Further to our becoming aware of correspondence between yourselves and EMR over the 170/5s, we would be happy to require EMR to return all of them to you. We love seeing the misery within their Regional operations; and given they they have so many cancelled and short-formed services anyway, we might as well relieve them of a few more trains - the situation is that bad anyway that removing some more trains isn’t going to make too much of a difference.
You can expect EMR to return your 170s by the end of next week.
Kind regards,
DfT
