Both of these are long (too long to reproduce here!) but are very illuminating reads - suffice it to say there is a clear and strong vision for TfW to be an integrated organisation going forward.
Regrettably, it seems that the WG's strategy (and indeed, only viable strategy) is to use a small number of bus specialists to multi-skill existing rail staff to take on additional responsibilities, with a resultant lack of understanding of bus operations. This is because they inherited little in the way of bus expertise when they were created; some Welsh Government civil servants and Traveline employees. For joint rail and bus employees, the rail side of their work could receive more attention due to comfort through familiarity, the greater sexiness of rail projects and the greater funds available for rail.
They'd likely have trouble hiring bus expertise for the following reasons:
1. Bus companies are very slim now so not as much talent is available in general, and many are reluctant to invest in new talent
2. The last of the NBC and early dereg personnel are ageing out of the industry
3. Competition for talent is high due to multiple franchises coming on stream at once
4. Wales is not an attractive place to live for many people.
