@Maersk.146 Good that you point it out - it is indeed an optical loading gauge sensor on last pic.
Here in Estonia we have similar sensors and also x-ray devices on border crossing points.

Great view from this spot!

@Maersk.146 Yes I agree with you, It’s good to see these locos back in service again. There were total of 19 C30-7A locos exported to Estonia, initially they were used in freight service only about 5 years. In 2008 all of them were put to storage, due to downturn in freight traffic. It was more economically reasonable to use only C36-7i locos going forward, since they are more powerful and can be used in solo to haul long freight train.

At the moment there are plans to rebuild 7 out of 19 C30-7Ai locos, but if there is demand from other countries they might build more. Now one of them is rented and being tested in Ukraine.

@classick Yes this is Barstow old yard.

Operail C30-M 1559 "Rudolf" at Ülemiste freight yard 01 Apr 2020:
This loco was built in 1979, then used as Conrail 6580, later Norfolk Southern 8098. In 2002 loco was exported to Estonia where it served until 2008. Taken back to service in 2019 after major overhaul.
Upgrading works were done at Tapa workshops, only frame and bogies remain from original loco. New bodywork is by CZ Loco and diesel engine by CAT.

These are former Conrail/Norfolk Southern C30-7A locomotives, exported to Estonia in 2002-2003 and starting from 2017 they are rebuilt with new engines and bodywork.
