As someone who works in the media planning world (we plan where to stick the ads and buy them etc), I've had a look at some of the data on this. The TV is running nationally, even on channels where it could be regionally targeted to avoid wastage. For radio, it looks like national distribution as well, despite radio mainly being regional by nature. It is a very dubious bit of planning to say the least.
Sometimes you end up with national campaigns due to some distress inventory being offered up late on as a short term buy. Having spoken to friends on the sales side, these were planned and bought a while back, so this isn't the case here. I know the agency involved have paid above pool prices (market averages), so it hasn't been well bought.
The creative executions are brand ads as others have said, with no call to action to book online or to promote their ticketing services.
Nothing wrong at all with the creative work, it's a nice campaign. The media implementation defies any obvious logic, which means that it has potentially been poorly planned, or the client was keen to go national and briefed it in that way.
The latter would be surprising, but it can happen. As someone who now works with clients directly to audit their marketing, from the outside looking in, this is poorly implemented and doesn't appear to be a particularly effective way to support the business. Sometimes there are specific reasons for a particular approach, but my gut feel is that the change of media team from VTEC to LNER will be the cause behind this. They are currently pouring a lot of wasted money away with this campaign.
