I just saw DLA344 on the 250 this morning and I must say that logo looks fake.
It's not the first time I've seen this logo being used, I have also seen the exact same logo on one of CN's PDL's (the ones for route 450) as well.
Same here, I think PDL134 might have one.
So it isn't just me then ;D
Come to think of it I remember one of The Shires' DLAs having this odd logo as well, but I didn't report it at the time as I thought it didn't matter that much; however seeing DLA344 made me post it anyway...
I thought I saw another DLA with Kent Thameside with the same logo too but I'm pretty sure I was imagining things there
