Lecture 15 - Main Line + Metro trains

Question 1

Class. of Railway vehicles acc. to EBO

Answer 1

Traction units: Locomotives, small locomotives, railcars

Wagons: Passenger coaches, goods wagons

Question 2

Working and special purpose vehicles

Answer 2

track laying machine, road rail excavator

Question 3

Characteristics of the locomotive hauled trains

Answer 3

High axle loads -> high tractive force
Low adhesive weight -> low accelerating and climbing capacity
Locomotive changeover necessary at the terminal station for driving into opposite direction
Flexible train composition

Question 4

Classification of Locomotive Axle Arrangments.
Explain what is a Co’Co’, Bo’Bo’, 2o’2o’, 2’C1’
(15.1)

Answer 4

A - one driving wheelset
B - two driving wheelsets
C - three driving wheelsets
o - individual axle drive
1 - one trailing wheelset 
2 - two trailing wheelset
' - wheelsets arranged on a frame (boggie)
\+ - permanetly couple separate vehicle parts
Letter: driving wheelset (filled)
number: trailing wheelset (no-filled)

Question 5

Categorization of Locomotives

Answer 5

Heavy-freight, freight train, mixed-traffic and express, mixed traffic, shunting and maintenance locomotives

Question 6

Characteristics of Passenger Coaches

Answer 6

One floor:
\+ moderate weight
\+ moving around is relatively comfortable 
\+ spacious interior
\+ slight rolling motion
- relatively uncomfortable boarding
- relatively low passenger capacity

Two floors:
\+ relatively comfortable boarding
\+ High speed capacity
- relatively high weight
- access to upper deck relatively uncomfortable
- confined interior

Question 7

Freight wagons

Answer 7

Four-axle container flat wagon
two-axle sliding wall wagon for break bulk
two axle double deck carrier
four-axle bulk freight wagon for dump material
two-axle tank wagon
single-axle flat wagon

Question 8

Individual vehicle arragement vs Jacobs arragement

Answer 8

+ Self supported coaches, longer coaches, less vertical bending or car body
- more bogies, more expensive, heavier train

Question 9

Advantages of Multiple units over locomotive hauled wagon trains

Answer 9

Lower axle loads, distributed traction, higher adhesive weight, good accelerating capacity, bi-directional vehicle with two driver cabs, inflexible train composition

Question 10

Word’s fastest trains

Answer 10

Speed record:
Japan 603 km/h
France 575 km/h
China 501 km/h
South Korea 421 km/h
Spain 404 km/h
Italy 400 km/h
Germany / Belgium 368 km/h
