Not quite, the 1st class ‘offer’ on the Norwich servces (except the evening booked 321 diagram), is complimentary refreshments, WiFi, air conditioning, tables to work on, power sockets. When 321s substitute, (unless a Renatus unit is provided and as only around 25% of that fleet are refurbished then you will only get WiFi, air con and tables), none of the above is provided plus there are only 32 First Class seats in an 8 car 321 compared to over 70 on a hauled set. Yesterday the two sets provided were non refurbished, as is quite often the case, so if you have a First Class ticket when a 321 is provided you run the risk of not only not getting the extras you’ve paid for but not even a seat in the class you’ve paid for. Yes substitution is better than cancellation but it’s not the same. Plus every substitution in the peak means that a couple of actual suburban services will almost certainly be short formed 8 vice 12 or 4 vice 8 to free up the units to run the Norwich.
