Graffiti is considered to some as an art, but growing up I never liked it and I will not endorse it. It may look good on the trains, but for the ones that had to live through it, sit in it, ride it to work, etc. it was not a happy time.
I saw the videos on YouTube of the graffiti laced trains and I must admit, we have it a lot better now, with the newer stainless steel SMEEs and NTTs. If you want to keep it on the train then that's your choice. It's considered vandalism, but it was also a focal part of our past.
Anyway, the R30 exterior could use some work, but since it just started i'll spread my best wishes.
