"On time" or "On Time"

[Bletchleyite]

Curious thing I noticed today.

At Bletchley, where things were performing fine, all the LNR services on the PIS were showing "On Time" with an upper case T except the Marston Vale which was showing "On time" with a lower case T. This seemed to be the case for all Marston Vale services.

Any ideas why that might be? Seems odd.

Maybe they run off different systems? (Pure speculation, but I’m assuming the Marston Vale signalling is rather different from the main line services, and so maybe they use different systems.)
