We鈥檙e less than a year out from the next Senedd election, when people in Wales will head to the polls.
Labour has been in power in Cardiff since the Senedd鈥檚 creation in 1999.
But the Labour Party on both ends of the M4 is acutely aware of the genuine prospect of a change in government in Wales, after a poll last month put Labour in third place.
Meanwhile, Nigel Farage kicked off Reform UK's plans to win the Senedd earlier this week in Port Talbot, where he pledged to try to reopen the blast furnaces there.
With all that in mind, Rachel Reeves is expected to pledge extra rail funding for Wales as part of her spending review this lunchtime.
The money 鈥� expected to be at least 拢445m 鈥� will go towards building new stations, upgrading lines and fixing level crossings.
Some of that money is expected to go directly to fund those projects, and some will go to the Welsh government.
It's hoped this will unlock economic potential, with rail projects in both the north and the south of the country.
Labour will argue the cash boost is as a result of the two governments, in Westminster and Cardiff, working together to deliver for Wales.
A Treasury source said Wales will "thrive" under the Labour Westminster government, and that the chancellor鈥檚 package "has the potential to be truly transformative".
But will the funding be enough?
Opposition parties say it won't, and claim that Wales is owed more.
Plaid Cymru say the spending review will "impose real terms cuts to many important services".
Ben Lake, the party's Treasury spokesperson, added that the re-classification of a rail line between Oxford and Cambridge to an England-and-Wales project would mean the country "loses out on millions in investment".
The row over that project followed a similar debate over high-speed rail project HS2, linking London and Birmingham.
HS2 was classed as an England-and-Wales project by the Conservative government.
If a project is classed as England-only, Wales鈥檚 devolved government gets a population-based share of funding, as was the case in Scotland and Northern Ireland.
But England-and-Wales projects are considered to benefit both nations, so the Welsh government gets no extra cash from them.
The Welsh Conservatives have described the spending review as a "kick in the teeth to the people of Wales".
Their leader, Darren Millar, said the promised investment fell "well short of the 拢1bn plus in rail funding planned by the previous UK Conservative government".
The Welsh Liberal Democrats鈥� Westminster spokesperson, David Chadwick, said Wales had been given "the scraps".
He said the funding "falls far short of the billions owed to Wales over recent years" and called for the full devolution of rail to Wales.
