Hi Junior,
The job involves sweeping, mopping, emptying bins, cleaning of onboard train tables, internal window frames and toilets. The toilets on the trains empty its waste on the track whilst moving, hence the sign on outside of toilet asking you not use the toilet whilst train is stationary, to avoid waste being emptied on track at station. You only clean trains and not platforms or station itself, as this job is been done by another company like iss/initial. Its not a difficult job and you are always working with someone, whether you are based at a station or depot.
I highly recommend job, my week working with Northern was one of the best experiences and Northern staff are friendly supportive and have a sense of humour.
Hope the above information helps.
