Here is a photo of Pennsylvania Railroad engine #4808, a GG-1 (2-C-C-2) built by General Electric in June of 1935, rated at 4,620 horsepower, and retired in June of 1966 after 31 years …

This is a roster of all GG1s produced, thier history and disposition. This page was updated 1/22/03. last to loose 5 stripe scheme. Attended 1949 Chicago Railraod Fair, wore Savinags Bond livery.

Many units wore variations to these liveries for part of their careers; variations are listed under “Notes” Stripes post-PRR = unit relettered for PC, AMT, CR, and/or NJT but retained PRR broad stripes

Pennsylvania Railroad No. 4846 was a Pennsylvania Railroad Class GG1 electric locomotive that was built by the Pennsylvania Railroad themselves at their own Altoona Works in May 1935.

Pennsylvania Railroad 4800, nicknamed "Old Rivets", is a GG1 class electric locomotive located at the Railroad Museum of Pennsylvania, outside of Strasburg, Pennsylvania in the United States. It is the prototype GG1 and was originally numbered 4899.

摘要: 伪响应调节因子 (Pesudo-Response Regulators,PRRs)基因是植物光周期开花调控途径中的关键基因。 本研究根据前期对GmPRR家族基因单倍型的鉴定结果，筛选出在编码区存在变异的5个GmPRR基因，开发出竞争性等位基因特异性PCR (Kompetitive Allele Specific PCR,KASP)分子标记，即GmPRR4-KASP、GmPRR8-KASP、GmPRR10 …

The PRR’s efficient electrification system, and its ability to help keep trains moving on the east coast, is credited with having prevented nationalization of the railroads as had happened in World War I.

2006年4月15日 · The true functional role of this receptor may therefore be to modulate the infectious disease process after TLR4 has been activated to produce cytokines such as IFN-γ. The production of IFN-γ will enhance PRR-driven production of antibacterial mediators such as NO (46) to clear bacterial infection.

Shown here (L to R) are Pennsylvania Railroad engines #4804 and #4886. Both are GG-1 (2-C-C-2) electrics rated at 4,620 horsepower each. #4804 was constructed by General Electric in June of 1935 and retired in June of 1966, while #4886 was built in Juniata during March of 1939.
