(a) Four ways registered mail differs from ordinary mail

1. Record of posting: Registered mail is recorded and a receipt issued at the post office, whereas ordinary mail is posted without any record.
2. Compensation: The sender of registered mail is entitled to compensation if it is lost or damaged, while ordinary mail carries no such guarantee.
3. Cost: Registered mail attracts an extra fee in addition to normal postage, whereas ordinary mail requires only the ordinary stamp.
4. Signature on delivery: Registered mail must be signed for by the receiver as proof of delivery, while ordinary mail is simply dropped in the box or handed over without a signature.

(b) Transporting goods by rail

Two advantages

1. It is suitable for carrying heavy and bulky goods over long distances at relatively low cost.
2. It is fast and runs to a fixed timetable, and is less affected by traffic congestion.

Two disadvantages

1. It offers no door-to-door service, so goods must be moved to and from the station by other means.
2. It follows a fixed route and cannot reach places not served by a railway line, and it is unsuitable for small or urgent consignments.
