Good evening Toad2017. Anytime I have been across to Tonbridge the West Yard has mainly been a combination of GBRf 66's and 73's. Lately there has been a lot of RHTT activity but I am not sure if this is still happening. Usually plenty of wagons in the yard but I am afraid my entire knowledge of what they are used for could be written on the head of pin!
If you click on the link below and scroll down the feed there are plenty of typical Tonbridge shots to give you a flavour.
