most of the engines are left outside running when it's cold. Crews will usually shut them down and pull the battery switches if the temperature is above freezing.

Yes, diesel engines are always running in case you didn't know! We don't see any other type of train doing this, but only diesel locomotives leave their engine running always. In case you haven't noticed, diesel trains are never turned off. They are always left running.
However, besides temperature there are other reasons to leave an engine running. Among these are to preserve a supply of air to the trains air brake system or to ensure the locomotives batteries remain charged.
Starting up a cold steam locomotive can take hours to build up enough steam to get it to move. No, it is not true that a train engine is never shut down. Train engines, like any other machinery, require regular maintenance and servicing, including shutting down the engine when not in use.
Engines may be left idling to maintain important safety related functions such as maintaining engine temperature, air pressure for the brake system, the integrity of the starting systems, the electrical system and providing heating or cooling to a train's crew and/or passengers.
The life expectancy of diesel-electric and electric locomotives is expected to be similar—about 25 years. Both types of motive power are subject to technological obsolescence.
Standard trains do not operate around the clock and usually start running at around 05:00 stopping again at 01:00. The main exceptions to this are certain airport services and London Underground's Night Tube - these run for longer periods, but depending on the service, may still take a few hours off.
Since British trains run on the left, the up side of a line is usually on the left when proceeding in the up direction. On most of the network, up is the direction towards London. In most of Scotland, with the exception of the West and East Coast Main Lines , and the Borders Railway, up is towards Edinburgh.
Fact #4: Trains Can Stop, But Not QuicklyThat's the length of 18 football fields. So if you think a train can see you and stop in time, think again. Trains cannot stop quickly enough to avoid a collision, which is why vehicles should never drive around lowered gates or try to “beat” a train.
Similarly, a typical train might haul 3,000 tons of freight 500 miles and consume approximately 2,885 gallons of diesel fuel. The efficiency of this freight haul would be calculated as: (3000 tons x 500 miles) / (2,885 gallons) = 520 ton-miles per gallon.
Modern locomotives use electric traction instead of gears as electric traction is much more flexible than gears. Diesel fuels generators from the combustion engine and transform the energy using an alternator, which runs the traction motors.
How Long Does It Take a Train to Stop? Trains can't stop quickly or swerve. The average freight train is about 1 to 1¼ miles in length (90 to 120 rail cars). When it's moving at 55 miles an hour, it can take a mile or more to stop after the locomotive engineer fully applies the emergency brake.
Travelling in the UKIf you miss your next train because a previous connecting train service was delayed, you will be able to travel on the next train provided by the train operator (if the entire journey is booked under one ticket).
The train whistle, or horn, is an important part of our safety practices. The horn alerts people that a train is approaching a railroad crossing. It can also be used to warn animals or trespassers in our right-of-way along a section of track.
The HS1 line is used by Eurostar services and Javelin commuter services from Kent, although the latter have a max speed of 140mph. Across the rest of the UK, trains have a maximum operational speed of 125mph, although many are capable of speeds of up to 140mph.
Maintenance: Trains may run at slower speeds at night to allow for track maintenance or repairs to be carried out more easily and safely. Schedule: Running trains at slower speeds at night can help to keep schedules on track, allowing trains to make up time lost during the day or to avoid delays caused by heavy.
The National Highway Traffic Safety Administration (NHTSA) says approximately every three hours, a person or vehicle crashes with a train in the U.S. About half of all crossing collisions occur at highway-rail intersections with flashing lights or gates leaving nearly 1,000 people dead each year as a result.
A caboose is a crewed North American railroad car coupled at the end of a freight train. Cabooses provide shelter for crew at the end of a train, who were formerly required in switching and shunting, keeping a lookout for load shifting, damage to equipment and cargo, and overheating axles.
