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 is not a proper inter-city train. The 5+5 and 9 car DMUs are almost as bad.
