Some years ago, the manufacture or import of certain fluorescent lamps was prohibited for energy saving reasons.
Mainly the fatter tubes, one and one half inches in diameter, known as T12.
Existing stocks could be sold or used without concern, but availability is now declining.

These lamps are used in some older trains. So if you are involved in any preservation group, you may wish to stock up if your rolling stock uses these lamps.

Also be aware that older mains voltage fluorescent light fittings in heritage railway buildings may use these lamps. In SOME CASES the newer type of slimline lamps can be used as replacements in mains fittings but NOT ALWAYS.
If the fitting uses a starter, then a slimline lamp will usually be fine, but starterless fittings may need the older T12 tubes.

A proper intercity train has a minimum of 8 coaches, gangwayed throughout, with first at one end, and a full sized buffet car between first and standard.
It has space for cycles, surfboards,luggage etc.
A 5 car DMU (Diesel Multiple Unit) is not a proper inter-city train. The 5+5 and 9 car DMUs are almost as bad.

Worth updating this old thread to add,

That the older types of fluorescent are now in very short supply and hard to find. If you are involved in a preserved railway or other enterprise that uses these lamps, stock up if you can, or look for alternatives.

And it has recently been announced that the newer T8 fluorescent lamps are to be banned in a couple of years time. Time to consider alternatives or to stock up.

Of particular importance for heritage railways is lighting of Mark two BR (British Rail(ways)) coaches. Many of these use fluorescent lamps. LED conversion units are available BUT MAY NOT WORK CORRECTLY OR AT ALL in railway light fittings as these use battery ballasts.

Most heritage railways accept the use of modern lighting in workshops, so that should be of little concern.

Old fluorescent lights in booking offices and waiting rooms might be a problem, stock up on spares.
