Attaining Necessary Permission to Shoot on the DLR

I have done some research and it has become clear that TFL are extremely strict in their regulations regarding filming on public transport. It appears we have to fill in this application in order to gain a student permit to film. It also appears that, according to TFL's Guide to Filming, it will cost £40 and be valid for one month from the date of issue. Therefore, it seems we must seek some funding as well as making sure that we have the necessary forms sent in. We will also need to make sure that we talk to certain people as the terms and conditions of the permit state that we must talk to the Station Supervisor in order to gain permission to use a tripod.
