Question

What is the difference b\w a mail and a express train?

Answer 1

In Britain, an express train is a class 1 train which is usually a principal passenger train, often a named one linking e.g. the Capitals and/or 2nd Cities of England, Scotland or Wales.

A class 1 train has priority over all other trains and in the days of steam and early diesel usually carried one headlamp over each buffer.

Now to confuse matters, mail trains were also class 1 trains which meant they were classified as express passenger trains (some had limited passenger accommodation). They were given this classification because they had to run at top speed with top priority to deliver the mail efficiently. Any train could carry mail, a practice which dates back to 1830 on the Liverpool and Manchester Railway, but dedicated trains for carrying mail soon appeared. 1839 saw the first Travelling Post Office (TPO) and a decade later, the first such vehicle fitted with pick-up and set-down equipment for exchanging mail on the move.

There is an excellent documentary film called 'The Night Mail', made in 1936 by the General Post Office (GPO) and the London Midland and Scottish Railway (LMS) which shows the principal mail train running between London and Scotland and covers all aspects of operating and working in such a train. They mostly ran at night and carried teams of postal workers who sorted the mail en route and collected and dispatched it using the pick-up and set-down gear.

Another feature of the TPO was that anyone could post a letter at a railway station (it had a letter box fitted on the side) and it would arrive at its destination neatly franked with the special mark used on such vehicles.

I Think Mail Train is Male Train and the Express Train is the Female one....

OK coming to the point   :  

Express trains (also sometimes referred to as "fast trains") are a form of rail service. Express trains make only a small amount of stops, instead of stopping at every single station. In many cases, trains often run express where there is overlapping local train service available, and run local at the tail ends of the line, where there is no supplemental local service. During overnight hours, or other times where it is practical, express trains become local, but still running to where an express train would terminate at.

the mail stops at very few stations whereas express stops at little more stations,also mail carries the postal mail
