I am going through my image sources to try to determine when features were modified on 11672.
The modifications include the following:
1) Original Headlights replaced by Halogen (Rectangular)
2) UIC Socket and Handrail (was this done prior to or simultaneously with 1)
3) Air Conditioning installed (Modified Shell)
4) Received Cargo livery and renamed 620 072 on 12/13 May 2020
