Im still not sure how this is likely to release DMUs for Caldervale services though. As I understand it, the only time DMUs are used on the West Yorks and Leeds-Doncaster services is when they are deputising for unavailable electric units
This is my confusion too.
The EMUs run self contained routes, and are all four coaches; any DMUs running on EMU routes are fairly rare (from my experiences).
Good that there are more peak services, of course. There's potential for slightly more EMU use (e.g. cut the Leeds - Skipton - Lancaster/Morcambe service at Skipton and run more EMUs from Leeds to Skipton, cut the Sheffield - Doncaster - Adwick service at Doncaster and run more EMUs from Doncaster to Adwick, but these are both very marginal and would lose through links). Really, we need electrification (e.g. Harrogate branch) to really benefit from more EMUs.
However, I must take issue with this quote:
They form part of the 650 additional carriages the Government will introduce onto the UKs rail network by 2014

Are you claiming that these cascaded EMUs from ScotRail are "brand new"? Because, unless I'm missing something, these aren't "additional carriages" on "the UK's rail network", just ones moved from central belt Scotland to Leeds.
Overall, good news, of course, I'm just confused by how the additional EMUs can be used on daily offpeak services or where these DMUs that will be cascaded to the Caldervale line will come from.
PS: Does this mean South Yorkshire can stop paying part of the leasing costs for the fourth coaches of the 333s (which are hardly ever in South Yorkshire)?
