RTT showing the following services cancelled today:

1217 Newcastle to Ashington
1300 Ashington to Newcastle
1847 Newcastle to Ashington
1930 Ashington to Newcastle
1949 Newcastle to Ashington
2030 Ashington to Newcastle
2216 Newcastle to Ashington

The above would mean that there's a 2.5 hour gap in trains to Newcastle from Ashington between 1900 and 2130, and that the last train of the day is also cancelled. Reasons given are issues with crew on each of them as far as I can tell. Anyone know if this is correct? Seems reasonably poor for week 1 of running the service.
