This is a reskin of the E231-500 Series made by Rizky_Adiputra and avaible on his website (jirctrainz.com).
All the necessary dependencies are included in this .rar, included in the original content’s package or avaible on the DLS.
In 2001, two 209-500 Series sets were transferred from Mitaka depot (Chuo-Sobu Line) to Urawa depot, to supplement 209-0 Series trains during the renovation works of the Keihin-Tohoku Line (wich, among other things, were in preparation for the D-ATC system, wich was enabled in 2004), followed by three more in 2006, to replace the three 209-900 Series prototype sets of 1992.
With the arrival of E233-1000 Series trains in 2007, the small Keihin-Tohoku Line fleet of 209-500s was gradually transferred again, this time to the Musashino Line (except for one set wich was transferred to the Keiyo Line and one wich was returned to the Chuo-Sobu Line, but moved to the Musashino Line as well in 2018).
By late 2009, no 209-500 Series trains no longer operated on the Keihin-Tohoku Line, and the retirement was finally formalized when the last set was moved from Urawa depot on the 24th January 2010.
Set No.15 (209-515) was transferred between depots no less than five times.
