I would amend these on the catering side (with the obvious safety critical roles of TM and Driver being on all) to:
| Five Car | 3 Hosts | 2 first class, 1 bar, but one may float due to loadings, e.g., if standard is heavier they may help with the first service out of origin, then help at the bar most of the rest of the way |
| or Five Car | 2 Hosts | Only Sundays generally run with only 2 Hosts, and do so especially on lighter loaded services in the middle of the day. |
| Nine Car | 4 Hosts | 2 first class, 2 bar |
| or Nine Car | 1 CEL
3 Hosts | 2 first class, 2 bar |
| Nine Car – Dine Menu | 4 Hosts
1 Chef | 2 first class + chef, 2 bar |
| or Nine Car – Dine Menu | 1 CEL
3 Hosts
1 Chef | 2 first class + chef, 2 bar |
| Ten Car | 1 CEL
5 Hosts | Cannot run without CEL. FRONT 5 will always have the CEL, and 2 other hosts with same premise as 5 car, and REAR 5 will have 3 hosts, also same as 5 car |
| Ten Car – Dine Menu | 1 CEL
5 Hosts
2 Chefs | Cannot run without CEL. FRONT 5 will always have the CEL, and two hosts + chef, REAR 5 3 hosts + chef, organised as they see fit based on loadings and similar premise to general five cars. (There were some of these with LDS crews in the morning, but not sure if any still exist) |
The only time these are generally deviated from are over the summer with some services given an extra host for part or all of their journeys.
As some have pointed out, there may be an additional 1 host, or even an extra full trains worth of them 'repositioning'. At LNER hosts do not 'pass', they are diagrammed 'assist' which might mean there are lots about, or they might just be sat down if the crew working the train decline their assistance.
10 cars cannot run without a CEL, and that cannot just be a host covering (as it could be on 9 car, with their being no additional responsibilities other than 'organisational' on those) due to the additional training a CEL has.
I also do not know how the new NCL-YRK shuttles fit into these, with them only being a 5 car and only an hours journey, so it would either be 2 or 3 hosts, possibly depending on predicated loadings when diagrams were made.
As also mentioned, if a first class is full leaving KGX on a Dish Menu for example, 3 hosts may remain in 1st until the first service is done, leaving it much more manageable with one cooking, one taking orders, and one running drinks, then after the first service one host going down to the cafe bar which depending on the standard loading could explain why at seat is not always available till a little after departure from origin and major stations.
I can't comment on at seat just not been on at all, because sometimes it is just technical issues, to crew shortages, to queues at the cafe bar, or lots of orders and not enough room in the microwave, but I'd say the general view onboard always used to be it's better for it to be off, than there be a 30 minute wait and customers running down to cancel their orders because they no longer have time to eat it before they get off. They're not always the reasons though, and it's generally best to speak to the TM if you have a question about it, because they're more likely to do something than the person with the switch who doesn't want to.
