Pointless signs - Leighton Buzzard

This from Steve...

Eye readers be interested in this photo of the platform screens at Leighton Buzzard (taken on 9th Dec 2010, and apologies for having taken so long to submit it).

The reason for the delay to the 08.34 (normally a 8-car Desiro, and indeed it seemed to be on that particular morning too) makes me wonder if London Midland and Siemens have already jumped on the bi-mode bandwagon?
