notbeappliedtocon ictwith it.Thismeantmouldings andpanelsshoulduselining toemphasisetheiroutlines. Nowadaysnoneofthisapplies andtheabsenceofliningin myviewisnotintheslightest waycompensatedbygarish colourstripesandblocks withoutconnectiontothebasic structure,appliedsweeping overtheunderlyingshapeeven togoasfarastocoverthe windows,thusruiningtheview frominside.The rststirrings ofthisdeclineappearedinthe thirtiesataboutthesametime asthetramcardesignsalso developedandmetalreplaced wood.Streamlining,although actuallyridiculousand expensive,wasadoptedand paintschemesfollowed.

The rstattemptsto modernisetheexistingtrams wastoremoveliningand adoptmodernsansseriffonts. Somestreamlinedtramswere introducedwithmouldings curvedtofollowtheformofthe streamlinedpro le.Donewith carethiscouldbeattractive (photo37).Traditionaltrams weregivenappropriate paintworksuchascurved liningsandtrianglesondashes inafutileattempttosuggest aspeedpotentialthatdidnot exist.Thesewere,onthewhole, notseriouslydetrimentalto thevisualquality,eventhough, whereliningwasstillapplied, the rstsignsofarelaxed attitudetoitsuseappeared.
