Getting around the UK
By bus and coach
in the UK, long distance express buses are called coaches. These are always economical, but they can be very slow. The biggest company is National Express, which has frequent services between big cities. They're usually cheaper If you buy your ticket early and travel at quiet times. In many towns, there are separate bus and coach stations, so passengers need to make sure they go to the right place to get their coach.
By car
Car travel in the UK is expensive, and there is often a lot of traffic. However, travelling by car means that you can be independent and flexible, and a car carrying three or more passengers can be cheaper than public transport. Motorways take drivers quickly from one city to the next, but small roads are often more scenic and fun. Parking in the centre of big cities can be difficult and very expensive, so an alternative is to use a Park & Ride. This is a system where drivers pay less to park their cars outside the city and take a bus to the centre.
By train
Trains are generally faster and more comfortable than coaches for long- distance travel, but they can be a lot more expensive. About 20 different companies operate train services in the UK, so the system can be quite confusing. However, passengers can get information on timetables and fares from the National Rail Enquiries website, which also has a way to buy tickets. There are two types of ticket: first and standard, and tickets are much cheaper If you buy them early.

Read the information again. Write T (true) or F (false).
