Strood Rail Replacement

[JFO]

I was in Medway on the 25th, and amongst other things I checked out the Medway-Gravesend rail replacement which an ongoing series of weekend blockades until July, which Strood Station staff told me is due to works on Higham Tunnel.
The operators seen included Travelmasters, 1st Bus Stop Bus Travel, Abbey Bus Travel and GO Ahead who brought a wide variety of vehicles including Wright Streetlite WS139 SM19KKC, a type I have never seen GO Ahead use on RR in our Area.
