Planning your journey is an essential part of travelling and if you are intending to use public transport most service providers have information lines and contact details. Make use of these and get as much information as possible, but most importantly make their staff aware of your visit and your need.
If travelling by train you may want to make contact with the National Rail Access Team who can give you advice and can send you information in various formats.
Most local authorities will have information about local travel and accessibility on their websites so that’s worth a check too.
Plan ahead and always take a contact number with you in case you get lost, are going to be late or have any access problems when you get to your destination.
If you want to take someone with you this can be a good idea too and, if you need specific support getting about, its worth having a look at the governments Access to Work Scheme or checking with your local Jobcentre Plus.
If traveling in London, there is a great resource on the Transport for London website which is an online journey planner where you can specify your departure and arrival destination, but more importantly the type of access you need, I.e. step-free from pavement to platform or lift access.
Sometimes for important meetings such as an interview it may be worth doing the journey once or twice in advance to make sure everything is OK for you.
Here are some useful websites for you but if in doubt or having any problems, contact the meeting organiser and they should be able to help you make arrangements.
