I’ve always loved trains. Perhaps it’s the
scale and power of the equipment. Perhaps it’s the history and variety of the
industry.
A couple of historical highlights that
appeal to me are: *
 |
| Regarded by many as The Ultimate Steam Locomotive of All Time - the vast "Niagara" 4-8-4 of the New York Central Railroad. |
 |
| The first main line diesel-electric in North America (Canadian National), No. 9000, built in 1929, and split into two units for operation following trial running. |
 |
| The Hiawatha Express Top: Class A 4-4-2 No. 1 near Dearfield, Illinois, 1939. Above: Class F7 No. 101 darkens the sky over Milwaukee as it pulls with Train No. 101, the streamlined 13-coach "Afternoon Hiawatha". |
 |
| The Swedish rod-drive triple-unit Class "Dm3" electric locomotives can produce more than 200,000lb of tractive effort. |

Speaking of trains, Tenova Takraf makes loading systems for railway cars. Tenova TAKRAF Rapid Rail Loading Systems use the flask loading system to load particulate material into moving trains:
- loading at rates of up to 8,000 t/h.
- handling a variety of rail wagons of different capacities and types.
- loading with accuracies, which meet most countries’ statutory requirements.
- allowing for a variation in material size and bulk density.
May 24, 2013 - More pictures added to this post; shown below.
The Tenova TAKRAF Profile Chute system,
through which material flows into the wagons, is self adjusting and allows for
differences in the heights of wagons to ensure the correct profile of material
in the wagons. The chute is designed to minimise potential dust emissions
during loading.
The Profile Chute is fail-safe in the event
of any electrical or hydraulic power failure. The Chute will automatically move
out of the way of rolling stock entering the rapid rail loading system bay.
SELF LEARNING CAPABILITY
The Tenova TAKRAF Rapid Rail Loading System
incorporates a programmable logic controller (PLC) and computer controlled
measurement system, which has a learning capability.
As the first few wagons are loaded, the
system assesses the effect of the loaded material’s density and flow
characteristics; the latter is affected by particle size, moisture, temperature,
etc. The system automatically accounts for prevailing conditions and loads
subsequent wagons to a high level of accuracy.
CONTROL SYSTEMS
Tenova TAKRAF Rapid Rail Loading Systems
are equipped with user friendly computer control, information and records
systems.
The accurate loading capability avoids
penalties because:
- individual wagons are not overloaded.
- axle distribution requirements are met.
- wagons are loaded to the correct height.
The control system is based on client
specified hardware and Windows™ based software allowing:
- overall SCADA control of the operation.
- automatic validation of truck numbers as they are entered into the SCADA system.
- visual monitoring of operations through closed circuit television systems.
Several optional facilities can be
supplied, including:
- uninterrupted power supply for computer systems.
- communication networks to the other computers, PCs or mainframes.
- communications with other weighing equipment on the plant to control reclaim operations.
- built-in mass calibration systems to simplify calibration.
