Api for TOPS/unit numbers

[Trains1]

hi all

I'm looking for an api to get the unit numbers of northern and gbrf trains. Up to now I've managed to get the train length from Darwin. I know rtt has this data but aren't lisnced to publish on their api.

Does anybody know of a way to acsses this information?

Thanks in advance.
