37117 and 56020 Doncaster Works
37117 has its gangway plated over, the Romanian grid is either 56010 or 56020 in for what is probably its first major overhaul.
Odds on it is 56020, the one in the background has white handrails for the record. The Romanian locos started off with black ones which were painted white at works visits.
Update, 56020 for sure, a slight bend in the handrail but a clear taper of the yellow below the drivers window matches up.
