it was the same for the last few groups , i waited nearly a year to get started and it was well worth it , from what ive heard and take what you want from this, theres a group starting sept for b,ham depots ,snow hill etc , then for depots further south a course will run in jan
i think it will depend on what depots you have applied for
but it is completely normal for this kind of long draw out process in general railway terms , in terms of LM the process isnt the best BUT having been through the process recently there is a lot of applicants for every role , there's a massive amount of planning etc
stay patient and if it works out for you then you will have a cracking job .
good luck
