I am adding little to that already debated, other than to note the subject of costs and how staggered I was when investigating the cost of a trip on the CS recently. I knew sleepers were expensive, but I was taken aback quite how much – looking at leisure travel and the somewhat romantic appeal of a trip to Scotland overnight by rail.
It was cost prohibitive for me. I wonder who is the majority actually booking and relying upon these spaces – and indeed who is paying for the journey, if not the same person? (i.e. are many of these bookings made by either people holding industry discounted travel authorities, or by employers sending staff to/from Scotland and funding that travel?).
On work travel, my employer has a generous travel policy and a number of staff north of the border who will travel to London on a regular basis, but even our budget would not stretch to the CS when compared to the option of having staff fly down in the early morning to London City, or take an early train getting them into the office in the late morning (as, indeed, generally happens).
Perhaps some employers are less flexible and require staff to attend at their usual hours, but ours will take the pragmatic view that a few hours later in the office to save some considerable spend on sleeper or an overnight hotel is overall better value to the business. Even travelling the previous day during the off-peak and funding a hotel may be cheaper at times, and not be particularly disruptive provided staff are able to check email and messages periodically etc.
