🔥 The British Rail Class 37 was already a beast, but this one has been taken to another level. With oversized turbochargers, flame-spitting exhausts, and a reinforced chassis, it’s putting out enough power to tow the moon. Some say it generates so much noise, it can be heard before it’s even scheduled to depart.

BR Class 33 was built for mixed traffic, but this version seems more interested in setting speed records on stout deliveries. With a few special modifications under the hood this Crompton is all gas, no brakes—unless it’s stopping for a Guinness. ☘️ 🍺

This Class 55 got a turbo boost. Rumour has it, it once outran the 125mph speed limit… in reverse. Photographer unknown. #Class55 #deltic #britishrail #trainspotting #railwayphotography #hotrod #trains”

When British Rail said ‘modernisation,’ they probably didn’t mean THIS. The Class 37 was already a workhorse, but now it’s a fire-breathing monster! 🔥💨🚂 Photographer unknown. #Class37 #tractor#britishrail #trainspotting #railwayphotography #hotrod #trains

With over 450 built, the British Rail Class 66 is a common sight on UK rails. But this one? Not so much. A few modifications to this shed means it gets from signal to signal before the dispatcher even notices.

British Rail Class 47: A workhorse of the UK rail network, but this one has been upgraded to thoroughbred status. Oversized turbos, flame-belching stacks, and an aggressive front spoiler mean it can outrun a Class 91 any day.

British Rail Class 60: Designed for heavy freight, but now tuned for pure performance. With twin turbochargers, a flame-belching exhaust, and enough torque to pull the rails off the sleepers, this tug isn’t here to mess around.

The British Rail Class 55 “Deltic” was designed with 2x Napier Deltic D18-25 engines. Most people thought this was enough, but this hotrodder disagreed and has fitted a couple of home made jet engines.

On Bonfire Night, we remember Guy Fawkes’ explosive plans—but the British Rail Class 43 (HST) InterCity 125 has its own way of making a scene! With a UK diesel speed record under its belt, it’s now putting on a fiery show of flames that even Fawkes would envy!

Beware the ghost trains of Britain that glide through the rails just once in a while, keeping abandoned stations and old lines alive in name only.

This railway photographer was undoubtedly disappointed when they found out their photo of a clagged up hot-rodded hoover had been ruined by the Northern Lights.

With only 2 or 3 cars per unit, getting a seat on a Class 158 can be described as “challenging” even taking in several factors, such as the time of day, the route, and how busy the service is.

This hotrodder has solved that problem by extending the car length from 22.57m to 33.69m.

They’ve also added flames on the outside to give passengers an idea of how hot conditions are inside because, being a 158, the AC almost certainly doesn’t work. #class158 #sprinter #dmu #britishrail #trainspotting #railwayphotography #modelrailway #hotrod #trains

Rail is already the greenest form of public transport, but the owner of this British Rail Class 40, wanting to hammer that point home, may have got the wrong end of the stick.

Cavalex Models recently released their 00 model of a British Rail Class 56 to much critical acclaim. What they haven’t released yet is this hot-rodded version, a prototype that is being tooled up right now, said to be their most accurately reproduced model to date.

The British Rail Class 20 is renowned for its distinctive single-cab design, which was done purely to cause arguments over whether it should be driven nose first, which looks way better, or cab first, which looks silly but at least the driver can actually see.
This hotrodder, having agreed with everyone that Class 20 cab looks terrible, has given his cab a nose job.

Captured here waiting at Edinburgh Waverly in May 2023, is the legendary British Rail Class 55 ‘Deltic’. This particular loco was unofficially scrapped a few years ahead of schedule in 1976 after a “clerical derailment” at Haymarket MPD meant that the whole body was chromed, instead of a few engine parts.
Thankfully it was salvaged by a railway hot rodder who proceeded to spend the next 7 years meticulously polishing it up before adding shark teeth to intimidate other slower train drivers into getting out of the middle lane.

Photographed over the weekend near Manchester by an unknown photographer, I think this locomotive was made after a British Rail Class 23 and Class 27 met and fell in love in about 1985.

But the best way to get the right answer on the Internet is to post the wrong answer. So I’m just going to call it a Class 88 and wait to get insulted in the comments. #class23 #class27 #class88 #babydeltic #babysulzer #deltic #trainspotting #railwayphotography #hotrod #trains

Nobody knows how many renumbering’s and liveries this British Rail Class 47 has had in its time but this one is still showing the younger trains how it’s done. #class47 #brushtype4 #duff #brush #trainspotting #railphotography #railway #railwayphotography #hotrod #trains

Rumoured to still be running on a branch line in Wales somewhere, the British Rail Class 142 is something that passengers would prefer to forget about.

One problem with Pacers was that they only had 4 wheels. This hot rodder solved that by adding a whole load more so now you can really feel every bump, rattle and shudder.

The squeal around corners is now louder than the fans at a Taylor Swift concert. #class142 #pacer #dmu #trainspotting #railphotography #railway #railwayphotography #hotrod #trains

The British Rail Class 50 was designed to haul express passenger trains at 100 mph.

What most rail enthusiasts don’t know is that they can actually go much faster than this if you only fit the same English Electric engine into each Mark 2.

If you’re taking your family out in this, remember to open the windows and bring ear defenders. #class50 #hoover #trainspotting #railphotography #railway #railwayphotography #hotrod #trains

The British Rail Class 08 are very popular amongst railway hotrodders, particularly those in the Age 17-21 age bracket.

This gronk, photographed resting at Crewe Works, has been modified with a 0-8-0 wheel arrangement.

I’m told on a good day, with the wind behind it, it can reach 31mph down Stoke Bank. #class08 #gronk #railwayphotography #trainspotting #hotrod #trains

The British Rail Class 91 is a fine locomotive but one big issue with it is its dependence on the overhead wire.

This hotrodder has opened up the entire network thanks to one or two small tweaks under the hood. #class91 #intercity225 #trainspotting #railphotography #hotrod #trains

With 455 in total built since 1998, the British Rail Class 66 is the most populous diesel locomotive in the UK. But this one is one-of-a-kind. Some say it outputs more CO₂ than the amount in the diesel it runs off of. Hotrodder unknown.

British Rail Class 43 (HST) InterCity 125, built by British Rail Engineering Limited from 1975 to 1982. Hotrodder unknown, but undoubtedly the larger high-performance wheels allow for a greater top speed than the stock 148 mph.
