toprovideeightcountiesinthegreaterDenverareawithbusandlightrailtransit.Theagency’s historyisintegrallylinkedtoDenver’seconomicandphysicaldevelopment,anditsvintagerolling stockisaniconicrepresentationofthathistory.Overthepastfewdecades,RTDhasacquiredseven vintagetrolleycarsandbusesthatarecurrentlystoredattheWestonDistrictmaintenanceand storagefacility.TheinventoryconsistsoftwoDenverTramwayStreetcars(nos.117and329),two DenverElectricTrolleyBuses(nos.519and553),aBritishBristolDouble‐deckerBus,andtwo Mackbuses(nos.132and140). Withnolong‐termplanforuseorrestorationofthestoredvehicles,aconstrainedbudget,and limitedRTDstoragespace,theoptionofdisposalbecameimminent.Inviewofthese circumstances,thePikesPeakHistoricalStreetRailwayFoundationhasinitiatedinterestin restoringanddisplayingthevehicles;theRTDBoardofDirectorsisevaluatingdonatingthestockto thefoundationforthesepurposes.Thisreportservesasdocumentationofthehistoryoftheseven vintagevehiclesremaininginRTD’sinventory. DocumentationandReportMethodology Tounderstandandconveythesignificanceofthevintagerollingstock,ahistoriccontextwas developedwithinwhichtheRTDanditsvintagevehiclescouldbeunderstood.Historiccontexts provideaframeworkforidentifyingandevaluatinghistoricresourcesthroughthefocused explanationofimportantaspectsofgeography,history,andculturewhichsignificantlyshapethe developmentofacommunity’sorregion’slandusepatternsandbuiltenvironmentovertime. Aliteraturereviewwasconductedtobeginestablishingthehistoriccontextfortheagencyandits vintagevehicles.InformationwasobtainedfromtheRTD,DenverTramwayHeritageSociety,the ColoradoOfficeofArcheologyandHistoricPreservation’s(OAHP)Compassdatabase,archivesat HistoryColoradoandtheWesternHistoricandGenealogyRoomattheDenverPublicLibrary,and historicnewspaperdatabases. Afteracontextwasdeveloped,fieldworkwasconductedincludingphotographicandwritten documentationofRTD’svintagehistoricrollingstockresources.Historicphotographs,schematics, newspaperarticles,andotherrelevantdocumentationwerecompiled.Onemajorresearchgapwas identifiedduringtheresearchanddocumentationprocess:primaryresourceswerenotidentified fortheBritishdouble‐deckerbus.AninterviewwithaformerRTDemployeelentsomeinsightinto thisparticularvehicle,asdocumentedbelow,andsecondaryresourceshelpedcompletethehistory; however,furtherinterviewswithadditionalRTDemployees/retireescouldprovebeneficialin fillinginidentifiedgaps. RTDVintageRollingStockHistoricContext ThestoryofRTD’svintagerollingstockisthestoryoftransportationinDenverbeginningwith cableoperation,convertingtoelectricity,andfinallytransitioningtogasolinepower.Theentire DenverstreetcarrailwaysystemhasbeendeterminedofficiallyeligibleforinclusionintheNational RegisterofHistoricPlaces(NRHP)(sitenumber5DV.9217‐DenverStreetCar/Tramway)under CriterionA.TheDenverstreetcarrailwaysystemplayedanextremelyimportantroleintheearly 3 transportationhistoryofDenverasitfacilitatedthedevelopmentoftheurbancenterandof suburbanneighborhoodsbyallowingresidentsaninexpensivewaytotravel. In1871,theDenverCityRailwayCompanybeganprovidinghorse‐drawnstreetcarsfor transportation.Around1890,afterenoughtrackshadbeenlaid,thecompanybeganoperating cablecar(alsocalledstreetcar)service.Meanwhile,acompetinggroupcalledtheDenverTramway Company(DTC)formedtoofferadditionalanimal‐andcable‐poweredcars,andalsobegan studyingelectric‐poweredtransportation.Milesoftrackswerelaidbybothcompaniesduringthis time.By1900,theDTCbeganconvertingitscablelinestoelectricoperationusingtheoverhead trolleysystem,andin1901theTramwayPowerfacilityopenedtobeginoperation.When electrificationwascompleted,cablecarsbecamesurplus.Somewereconvertedforelectric operationandthosethatwerenotwereburnedtosalvagemetalparts.

In1893,GeneralElectricintroducedacontrolmechanismforstreetcarsknownasthetype‐K controller,whichsogreatlyimprovedtheelectriccarthatmostAmericancitieswithcablesystems convertedtoelectricitywithinthefirstfouryearsofavailability.DTCwasoneofthefirstfirmsto electrify(Hilton1967,48).Eventually,theDTCconsolidatedwithitsrivalcompaniesandformed theDenverCityTramwayCompany,whichnowownedtheentire156milesofcityrailwaysystem. Thestreetcarsinheritedthecablecar’s3’6”gauge.TheSouthBroadwaylinewasthefirst electrifiedtrolleycarlinetooperateinDenver.ItcontinuedinoperationfromDecember1889to June1950.In1909,DTCpurchasedtheDenverandIntermountainRailroadandconverteditfrom steamtoelectricpower,providinganotherroutetoGolden,Colo.(onehadalreadybeen 4 established)aswellasabranchlinetoBarnum(Lusky1968).Peakperformancefortheelectric streetcarswasduringtheperiodbetweenWWIandtheendofWWII.
