Omaha at the NYMR
The North Yorkshire Moors Railway has completed the conversion of USATC S160 locomotive No. 2253 ‘Omaha’ from coal firing to oil, marking what is believed to be the first full-size steam locomotive oil conversion undertaken in the UK since the end of main line steam operations.
Built by Baldwin Locomotive Works in the United States, No. 2253 arrived in Britain in May 1943 for service on the LNER, based at Neville Hill depot in Leeds.
The locomotive was one of 800 S160s produced in North America for the United States Army Transportation Corps and shipped overseas during the Second World War.

Following the conflict, it entered service with the Polish State Railway as TR203-288 before returning to Britain in 1992.
Ownership passed to Peter Best in 2013.
The conversion project was carried out by the North Yorkshire Moors Railway Engineering Department, with support from Tennessee-based FMW Solutions, a specialist in alternative fuel technologies and railway engineering.
Components were manufactured both in the United States and at the railway’s workshops in Grosmont.
As part of commissioning trials, the railway plans to use cold-pressed rapeseed oil supplied through Phoenix Group.
The locomotive can operate on a range of liquid fuels without modification.
‘Omaha’ is scheduled to re-enter traffic this summer, while longer-term plans include converting Austerity locomotive No. 3672 ‘Dame Vera Lynn’.
“Completing the oil conversion of No. 2253 is a huge achievement for the railway. This project not only advances our sustainability strategy by reducing particulate emissions but also ensures operational resilience during hot weather periods. With the cost and availability of high-quality steam coal becoming increasingly challenging, converting Omaha to oil secures the future of steam operations for our visitors and volunteers alike.”

TfW Class 398 Tram Train
Transport for Wales (TfW) is entering the final stages of preparation ahead of the introduction of its first brand‑new tram‑trains on Pontypridd to Cardiff Bay services this summer.
Training for traincrew is well under way, with test runs taking place most days.
TfW continues work to install nine new toilet facilities as well as five refurbished toilet facilities across the Treherbert, Aberdare and Merthyr lines, helping ensure customers have access to toilets when the tram-trains are rolled out.
The South Wales Metro aims to improve connections between Cardiff and the Valleys, with more frequent and faster journeys.
TfW’s new fleet of fully electric tram-trains are key to delivering this ambitious Metro timetable.
The improved performance of the new trains, combined with the improvements TfW made to the infrastructure, will reduce journey times to around 50 minutes between Cardiff and Treherbert, Aberdare and Merthyr, with a train every 15 minutes.
These changes will be delivered gradually in phases.
Tram-trains will also allow TfW’s network to be expanded, as they’re able to run on light-rail tram lines in the future, as part of the Cardiff Crossrail project.
This will allow even more communities to access vital rail services.
The tram-trains are designed for Metro style hop-on-hop-off journeys, with level boarding from train to platform, three open and spacious carriages and improved spaces on board for wheelchairs and bikes.
The first of the 36 new tram-trains will be introduced onto Pontypridd to Cardiff Bay services this summer, replacing the older Class 150 trains that currently run on these services.
Dan Tipper, Chief Infrastructure Officer at TfW said: “Our teams are working extremely hard as we move into the final stages ahead of introducing our first tram‑trains into service.
With driver and train manager training nearing completion and testing taking place most days, we’re making strong progress towards launching these services.
“The tram‑trains are central to delivering the faster, more frequent journeys promised by the South Wales Metro and, alongside pay as you go, will support a true turn‑up‑and‑go service for communities across the Valleys.”

New station toilets on the Treherbert, Aberdare and Merthyr lines
As with other metro systems across the UK and Europe, TfW’s tram‑trains do not have toilets on board.
Transport for Wales recognises how important access to toilet facilities is for customers and has made a significant investment to improve provision where the tram-trains will run.
This includes the installation of nine new station toilets across the network, alongside the upgrade of five existing facilities.
These improvements mean that customers travelling on tram‑train services should never be more than 20 minutes away from a toilet when travelling on the network.
Each of the newly installed toilets have been designed with accessibility in mind, including:
CCTV outside the toilets will be streamed live to TfW’s Integrated Control Centre in Taff's Well, where it’s managed 24/7 by a dedicated team.
Live help points will ensure customers can report any issues, and remote door locking aims to also help reduce vandalism and anti-social behaviour.
TfW will also employ mobile teams to keep the toilets clean and secure.
As installation of the new facilities progresses, with six of nine toilets now nearing completion, Transport for Wales will provide temporary facilities at Pontypridd, Trefforest and Radyr while existing toilets at these stations are refurbished.
These temporary facilities will open in time for the first tram-trains to enter service.
Further information, including maps showing the new toilet locations, is available on the TfW website - https://tfw.wales/south-wales-metro-toilets
Toilet facilities across the Treherbert, Aberdare and Merthyr lines will be in place before tram‑trains enter service on these routes, ensuring customers are no more than 20 minutes away from a toilet while travelling on the tram‑trains.
Each new toilet facility will open as soon as construction is complete, with toilets at Aberdare and Abercynon stations expected to be the first to open.
Over half of the new toilets have already been installed at stations, and work is ongoing to open the facilities in time for the introduction of the first tram‑trains onto the Treherbert, Aberdare and Merthyr lines.
For those travelling on board the tram-trains between Pontypridd and Cardiff Bay, passengers are advised to use customer toilets available at Pontypridd, Trefforest, Radyr, Cardiff Queen Street and Cardiff Central.
