Unimaginative Racism is Unimaginative

My message to Virgin Trains Customer Relations:

Hello,
I was on the [HH:MM] on Thursday, 7 July 2016, from London Euston to Birmingham New Street. I had booked Seat [XX] in Quiet Coach [Y]. Just above my seat on the Quiet Coach sign, someone had written "BNP". Someone else had tried unsuccessfully to scratch it out, but the graffiti, as shown in the attached photo, was still clearly visible.

As a mixed-race British citizen, I found this unsettling. I did not particularly enjoy sitting underneath a blatant piece of unimaginative racist propaganda for the entirety of my journey. Would it be possible for the sign in the coach of that train to be replaced? I presume there is a way of identifying which train was running that route at that time?
Thank you,
[nanila]
