Being multi modal is just combining travel methods.
Many train stations have park and ride facilities. Some days, particularly in winter in cold and/or wet weather the train can reduce the amount of driving you need to do. And, whilst still using your car, at least you are not driving all the way.
All stations now have cycle parking meaning that you can get to the station in a fraction of the time it would take to walk. You can walk 2 miles in 30 minutes or cycle it in about 12.
By making the shorter journey by foot or bike you don’t need to wear special clothes and through including active travel you’ll be healthier and fitter.
Whether walking or cycling, route calculators will help you find the best way and give you a good idea of how long it will take to get there.
Whether you are new or familiar to the area, CycleStreets.net can help you plan your route by bike whilst walkit.com can provide you with the best route by foot.
