ScotRail is a brand name which has been used by various operator companies over the years, including Abellio (part of Holland's national railways), Virgin Rail and others. The brand name remains, even as the operator companies may change depending on changes on public tenderings.

This three wagons long electric multiple unit is ScotRail's class 334. They were built by Alstom in Hungary, in Washwood Heath and in Birmingham as part of Alstom's Coradia Juniper train family. They were built 1999-2002. Just like all the other Coradia Juniper trains, these also had a lot of "children's diseases" so that their start in real use was much delayed. All these trains are owned by Eversholt Rail Group and ScotRail has merely a 30 years long lease agreement. These trains are three coaches long per trainset, with 183 seats and there were 40 trainsets built. Their power rating is 1080 kW, top speed is 145 km/h and they run with 25 kV AC on normal gauge 1435 mm. All of these ScotRail's units were totally refurbished 2012-2014 with a lot of changes, for example the couplings used between wagons were all changed.

Scotrail's class 170 diesel multiple unit, formerly called British Rail class 170 Turbostar, is a train that was constructed and built 1998-2005 by ADtranz/Bombardier. It replaced quite a number of old diesel train classes. It has two or three coaches per unit and it runs with MTU's diesel engines. Every wagon has one powered bogie. Originally 139 trains of this type were built.

This is how the class 170 trains used to look like in the old days when First Group was still the operator of Scotrail.

This is the same train as in the picture above. An old class 158 DMU was being towed at the end of the train.

Still the same train as above. Note the small text "Not in service" at the class 158 unit.

This is the old livery of Scotrail trains from those days when the franchise Scotrail was still operated by the First Group. Later Scotrail was taken over by Arriva UK and Arriva started taping/painting the trains differently with the Scottish flag as the main motive. However in the older DMU trains this First Group style livery remained a long time.

Scotrail's class 158 diesel multiple unit, formerly British Rail class 158 "Express Sprinter" is a predecessor of the class 170 shown above. They were designed and built by British Rail Engineering Limited (BREL) and ScotRail took the first ones in use in 1990. They are always two or three coaches long and motorised by either Cummins or Perkins turbodiesel engines. They were designed for regional express services, but today they serve mainly less frequented sidelines and secondary routes.

Scotrail's class 380 is a Siemens Desiro train although it bears no resemblance to the Desiros operating in continental Europe. 38 of these trains were ordered for the planned airport express service of Glasgow which however was never taken into use. Today these operate ScotRail services in the Ayrshire and Inverclyde regions of Scotland and formerly they were also used in the traffic between Edinburgh and Glasgow. 38 trains were built 2009-11. They are owned by the leasing company Eversholt Rail Group and Scotrail has just leased them. They entered service in 2010.
Picture from Edinburgh Waverley station 4.10.2017 by Ilkka Siissalo.

The front parts of these UK versions of Siemens Desiro trains are awfully ugly because of the tube connections that allow people to walk from one unit to the next one while the train is running. It has been proven time and time again that such tubes are very rarely really needed.

Crosscountry is a train franchising brand operated currently by Arriva UK trains. This train is a class 221 Super Voyager, a tilting, fast, five coaches long diesel train built by Bombardier in Belgium 2001-2002. 44 trains were built. There is also a shorter variant, class 220, which is just four coaches long and has somewhat different bogies (two of class 221 trains are also just four coaches long). The top speed of these trains is 200 km/h. They are powered by Cummins turbodiesel engines, one per every coach.
Picture from Edinburgh Waverley station 4.10.2017 by Ilkka Siissalo.

Crosscountry's class 220 is almost similar with the class 221 shown above, but the class 220 trains are only four coaches long. They also have different kinds of bogies, but that's difficult to spot from a picture like this. Luckily there's a text by the side of the train telling us that this indeed is a class 220 :-)
Picture from Edinburgh Waverley station 7.6.2015 by Ilkka Siissalo.

It takes a closer look to be sure that this one indeed is a class 220 train.

Transpennine Express is a franchise brand name of Transpennine Trains Ltd. and it runs services from central Britain, e.g. Liverpool or Manchester to destinations in the north, such as Edinburgh or Glasgow. This class 350 train is a Siemens Desiro, although it doesn't resemble continental Desiros in any way. Nevertheless, the technology is the same. These trains were built in continental Europe in several of Siemens' locations, such as Wien in Austria, Ürdingen and Krefeld in Germany or Praha in Czech Republic. These trains can run with 25 kV AC overhead or with 750 V DC from a third rail. Their top speed is 180 km/h. They were built since 2004. Today Transpennine doesn't use this train type any more.

In other parts of the world motorless coaches like this one are called control cab wagons or pilot wagons or driver's cab coaches but in Britain they are called DVTs, driving van trailers. Nevertheless, this is a nonmotorised wagon with just a cab and it matches the look and feel of an HST locomotive or a class 90 locomotive which powers the train at the other end. This one is a Virgin Rail's class 82 DVT.

Next to the DVT wagon this train had a wagon which was half a cargo wagon and half a passenger wagon.
Picture from Edinburgh Waverley station 3.10.2017 by Ilkka Siissalo.

Most of the train consisted of former British Rail Mark IV coaches which were specifically constructed for trains running over 200 km/h.

...and this was the other end of the same train, a locomotive of the class 91, this time pushing the train composition.
Picture from Edinburgh Waverley station 3.10.2017 by Ilkka Siissalo.

British Rail class 91 locomotives were built as high speed electric locomotives with a power rating of 4,7 MW and a top speed of 220 km/h, 177 km/h when pushing a train. They were designed by General Electric and built by BREL Crewe Works 1988-91. They were totally rebuilt and modernised by ADtranz 2000-2003. They were built for operating under 25 kV AC overhead catenaries and they were intended especially for the East Coast main line. These machines have also been known under the name Intercity 225.

The HST trains, also known as Intercity 125, are classic trains which are already so old that it's becoming quite rare to see one. An HST train consists of two class 43 fast diesel locomotives plus a varying number of Mark III wagons in between. The class 43 disel locomotives are still today considered to be the fastest diesel locomotives in the world. They were built 1975-82 by British Rail Engineering Ltd. Crewe works and there were 197 of them. Their top speed is 201 km/h (125 miles/h). This is a rarity by now!

The HST trains have always consisted of two class 43 diesel locomotives plus a number of these Mark III coaches in between.

These class 92 heavy electric locomotives were designed to be used in the Channel tunnel between Britain and France. 46 machines were built by ABB Transportation and Brush Traction 1993-96. They were intended for pulling both passenger and cargo trains, but since the planned Nightstar passenger sleeper trains through the Channel Tunnel never materialised, there were just by far too many of them. When new, these machines were divided between the French SNCF and British Rail but today some are operated by GB Railfreight, some by SNCF and some by DB which wanted to use them for example hauling coal trains from Romania to the port of Koper in Croatia. But now some of them have been sold even to Russian investors. Here we see one of them still in the original livery as they were when new. The class 92 is a two electric systems electric locomotive which can run either with 750 V DC from a third rail or from 25 kV AC overhead. GB Railfreight has been using some of these for pulling the "Caledonian sleeper" night trains of the company Serco between London and Edinburgh and that's why we see one of these "Chunnel" machines in Scotland.

Edinburgh Trams has one tram line linking Edinburgh airport to the city, but further lines are planned. The first line was taken in use in 2014. The trams are 42,3 metres long bidirectional CAF Urbos 3 trams made in Spain. They have a top speed of 70 km/h. There are 27 of these trams in use.
